Justin Wyss-Gallifent CMSC250 Expecting a B+ Anonymous 05/25/2023	Very nice professor. His lectures at 9:30am were engaging but I did fall asleep a couple times. He has a nice accent. The course was challenging and the final was much harder than I expected. I had a 98% going into the final because I did well on the two midterms and my grade dropped to a 86% which was a B+ so he does curve. Honestly, the bad grade on the final is my fault. I made a lot of silly mistakes and didn't prepare much. Other than the hard final, the structure of the class had groupworks which is basically just required discussion attendance (you can miss up to 4 without it affecting your grade). Homeworks were not very difficult but there would be times when the TA grading your homework would just be very picky about a certain problem. Kinda annoying especially when ur just skipping steps cuz you can do it in ur head. The pace of the class was a bit off but this was the second time he was teaching this class so it was reasonable. Felt like we were going really really slow at the beginning and then really really fast at the end. Wasn't terrible but skipped a lecture in the beginning and next one was still the same. Skipped one at the end and was lost at the next lecture even after looking at the lecture notes he posts after every lecture. Would recommend totally recommend. Be wary of his finals (the myths about his hard finals are true from my experience).
Justin Wyss-Gallifent CMSC250 Expecting a B Anonymous 05/24/2023	Justin explains concepts very well and his notes are very organized and clear. His exams are straightforward and he provides practice exams which are helpful. If you attend lecture, then the homeworks are easy to complete, as he goes over very similar examples.
Paul Kline CMSC250 Expecting an A Anonymous 05/24/2023	Amazing professor. Super helpful and approachable. I wish I could take more courses with him in the future, but I think he only teaches 250 since he teaches part-time. HW is a little tough in the middle of the course but if you go to TA office hours you will be fine. Great guy.
Paul Kline CMSC250 Expecting an A Anonymous 05/21/2023	Solid guy I'd say, some of his TAs go a little crazy on the homework but it got better by the end of the year. He teaches concepts really well, posts his slides and records lectures. Has a piazza which is helpful and all homeworks/exams are uploaded to gradescope to you can easily get regrade requests. He has style differences from his TAs which came to bite us on our third exam but its nothing to terrible. His exams are super fair/easy and his TAs often release hella practice material. Teaching is his side gig, he works at a software company but is a really good teacher. Also he is the biggest nerd known to man, 4.0s straight throughout high school and colleges, but in a cool way. I'd
Justin Wyss-Gallifent CMSC250 Expecting an A- Anonymous 05/18/2023	yea that final was pretty tough. But he's the GOAT.
Michael McCourt CMSC250 Expecting a B Anonymous 05/15/2023	Hey, are you a CS major? Are you looking for a FREE class? Look no further! I shit you not, this is LITERALLY the first two weeks of CMSC250. Unit 1 is truth tables (week1 of 250), Unit 2 is proofs (but in a different style than taught in 250, just read the textbook for 10 minutes) and the final unit is universal quantifiers (but with less restrictions). If you did 250, you can skip 98% of lectures. I literally don't have an A on this class solely because I kept forgetting it existed. Do the hw, do the quizzes, the whole workload of the course can be done in like 3 hours. About McCourt, seemed very nice and very helpful in lecture. Well, I only went like 5 times.
Evan Golub CMSC250 DenialWhammy 05/10/2023	The class is relatively simple for anyone with a background in math. Didn't go to lecture after realizing how simple the content was. However, I'm giving Golub 3 stars because the proofs are heavily reliant on proper syntax, so even if you get the right idea, you'll be docked points if you don't do it the way he does it. Find a way to do every problem he can give you, and copy it word-for-word, so you can throw it back during exams.
Cliff Bakalian CMSC250 Anonymous 05/09/2023	the structuring of this class was actually perfect. only issue was that he was very mistake prone and he didn't record lectures while kline did, which lowkey saved everyone
Justin Wyss-Gallifent CMSC250 Expecting an A- Anonymous 05/03/2023	I had no issues with him up till these homework, he shows how to do a certain type of question during lecture, then puts that type of question in the homework, and then takes points off when you do it how he did it during lecture.
Justin Wyss-Gallifent CMSC250 Expecting an A- dfesenko 05/03/2023	I believe Justin makes this class a lot more fun and interesting than other professors. The lectures are enjoyable, homework is not overbearing (one homework a week) and exams are relatively straightforward. Also no random quizzes during lectures unlike some other CMSC professors. 10/10 would take again and recommend to anybody choosing between professors. You won't regret taking this guy.
Paul Kline CMSC250 Expecting an A- Anonymous 04/25/2023	great professor but the TAs gotta chill on the hw
Paul Kline CMSC250 Expecting a B+ Anonymous 04/18/2023	Great lecturer and did a good job making the content of 250 seem really simple. There were times where what he was saying contradicted how the TAs were grading, but he was new and it never was that big of a problem. Great professor and cares
Evan Golub CMSC250 Expecting a B Anonymous 04/03/2023	Entirely invalidating proofs on exams due to minor mistakes at the beginning of proofs and destroying exam grade.
Paul Kline CMSC250 Expecting an A- Anonymous 03/29/2023	Had him for the first semester he taught. Did a really great job. His lectures were always clear, I would actually be enjoying the content because I was able to understand it instead spending the whole lecture confused and trying to figure things out. He had some really good TAs too that made it even better. I thought I would struggle going into the class based on the reviews for 250 I've seen before but It surprisingly went better than I thought. He was really down to earth and understood everything from the perspective of the students. 10/10 would do it again.
Cliff Bakalian CMSC250 Anonymous 03/12/2023	Cliff was super nice and chill. I honestly didn't learn a whole lot but I think that may be the way Discrete Structures is as a class. His hair is mad luscious too. The exams were online when I took it in spring 2022, and they were very fair. His class did kinda reward cheating behavior, but I didn't mind it personally.
William Gasarch CMSC250 Expecting an A Anonymous 03/10/2023	Incredible teaching!
Cliff Bakalian CMSC250 Expecting an A Anonymous 03/10/2023	Really nice instructor. He's quite approachable during his office hours and answers questions or explains concepts really well. He has started from the basics many times even though it's repetitive/obvious. His lectures were quite good and I enjoyed his classes.
Justin Wyss-Gallifent CMSC250 Anonymous 03/04/2023	I had Justin for MATH206, which I was able to finish in the 2 days before the semester started, and I also have him for CMSC250. He's a really great guy; I'd probably give him 4.69 stars if I could though, simply because I think he babies the class a little bit. Our first exam was ludicrously short and a ton of people were finishing with a full 40 minutes left. His lectures and notes are extremely organized, and you can get ahead of the game if you absolutely wanted to. Homeworks don't take more than 3 hours a week. Very talented at explaining concepts in a simple and concise manner.
Mohammad Nayeem Teli CMSC250 Expecting a B+ akl2025 02/20/2023	Professor Teli is fantastic. His lecture notes are neatly written and available on ELMS, and he provides clear explanations for every class. Additionally, his quizzes, midterms, and final exams are all fair, so I can't complain if I lose points due to my own mistakes. I also want to give a shoutout to my amazing TA, Emily Kaplitz. She's been incredibly helpful in our discussion section and has gone above and beyond to ensure that we all understand the material. I'm grateful for her support and guidance throughout the course.
Emily Kaplitz CMSC250 Expecting an A- Anonymous 02/10/2023	She is very knowledgeable on all of the course material and explains each subject very well. She cares deeply about your learning and also supports you. It's also super easy to talk with her. I would highly recommend her.
Paul Kline CMSC250 Expecting an A Anonymous 01/25/2023	Great lecturer, teaches well and is enthusiastic about the material. My only complaint with the class is that some of the exams, particularly questions on probability, were worded poorly. Still not going to dock a star because I think Paul is aware of this and working on it.
Paul Kline CMSC250 Expecting a C- Anonymous 01/23/2023	For Professor Kline's first semester here teaching, he did an outstanding job. He is extremely helpful in office hours and so are his TA's but I was rarely able to attend since my focus was on linear algebra(MATH240) and CMSC132. On of my biggest issues with the course was that there was a lack of practice material that was available online to prepare for much of the harder concepts in the course like induction or combinatorics. Start the homework early as you have a week to complete it. Youtube and Justin's Notes for CMSC 250 are your best friends to do well in the course. There are only two midterms so not performing well will drop you significantly. That first exam is not a joke as I did not prepare with enough time in hand and did very poorly. He is a very nice guy that wants his students to succeed and have no doubt he will be a top professor at UMD.
Mohammad Nayeem Teli CMSC250 Expecting a C Anonymous 01/23/2023	Yes the grade I got is a C. However Professor Teli is an amazing professor, a professional with indepth knowledge on the subject matter. The lectures are very relaxed and full of information that is relevant to the CS field and exams. However in application, is where your TA comes into play where they go over applying the concepts learnt in class in various scenarios. My TA, Yue (I hate specifying names but I feel is nessecary) did not teach a single thing and showed absolutely no interest in the subject or the class. I feel students should speak up because at the end it is our grade that is hurt not the the TA's
Cliff Bakalian CMSC250 Anonymous 01/03/2023	Decent instructor, but lectures can sometimes be boring. Exams (in-person) and quizzes (online) are fair but require studying. Weekly-ish homeworks were tricky at times but a few got dropped. Some TAs were very helpful and took time outside of discussion (which doesn't consist of graded assignments) for exam review sessions. The content itself isn't too difficult but can require some practice to understand. Would recommend taking it with him.
Cliff Bakalian CMSC250 Expecting an A Anonymous 01/03/2023	I wanted to like Cliff, I really did. He was a bad lecturer. He often got confused during lecture and his style was extremely different from what we were expected to replicate, making it impossible to do well in the class without studying the style guide. I stopped going to his lectures completely and instead watched Paul Kline's recorded lectures that we had access to while they co-taught. When I talked to him in person about issues with his TAs and their grading though, he was very understanding and willing to help with regrade requests.
Cliff Bakalian CMSC250 Anonymous 12/29/2022	I was really disappointed by Cliff's teaching. He seems like a really chill guy and was very helpful during office hours. However, his teaching was pretty uneventful. To begin, his slides were impossible to use. He decided to use reveal.js which, while being very sleek and clean, forced you to look through a 2D maze to try and find what you were looking for. Add to that transitions which prevented all necessary info from showing on the overview made it a mission to try and find a formula or method to do a problem. His lecturing wasn't fantastic either. He would mumble through his slides and not do a lot of in-class practice problems. A more class-wide issue was style. Having a style guide was very helpful in showing what would be accepted as homework/test answers. However, it would be more helpful to designate a specific way of doing a problem/signs to use to prevent confusion when one professor uses one symbol/method, the other uses different ones, and the TAs use whichever their profs used when they took the class. Although the previous gripes made the class frustrating, Cliff was very fair about how he ran the class. Each homework could get a 10% boost if you used Latex (which is not hard to learn/use) and almost every test/quiz had an extra credit question that was very possible to get right. He gave opportunities to submit homework late for full credit and even gave a supplement to a question on the first midterm that did not go well initially to boost test grades. He also gave a survey to gauge class satisfaction after the first midterm. All in all, a fair class but with sub-par teaching. 10/10 hair and fit though (worth an extra star).
Mohammad Nayeem Teli CMSC250 Expecting an A+ Anonymous 12/24/2022	Teli was doing so good in 250 this semester. His class is the most organized class compared to other classes that I was taking this semester. Quizzes were easy but sometimes challenging enough. Homework was not long and doable. He also gave us 1.5% extra credits which helped a lot. He revealed the cutoffs at the end and it's reasonable. Teli is also a good lecturer since I saw a lot ppl attend his lectures than in other classes. I got confused during his lecture sometimes, but it's acceptable.
Mohammad Nayeem Teli CMSC250 Expecting a B- Anonymous 12/24/2022	Teli was super nice and a great lecturer. Midterms and Finals were extremely fair. Quizzes were difficult for me but the homeworks were great practice for it. I'd take his class again.
Cliff Bakalian CMSC250 Expecting an A Anonymous 12/24/2022	Great professor who understands what the students are dealing with and changes/adapts to accordingly. This is only this second year teaching so there are a few rough edges but if you get in touch with him, he is more than happy to help. His slides could use a little more work especially towards the later chapters but at the same time, TAs release detailed notes on the topics discussed. There is also Justins Notes and the entire Fall 2020 250 class webpage to consult.
Mohammad Nayeem Teli CMSC250 Expecting an A- Anonymous 12/23/2022	Probably one of the best lecturers for CMSC250, you can understand a concept very clearly after a lecture - I can't say that I have had this experience with many other lecturers. The main issues in this class is a lot of times he assigns homework's with concepts that we barely covered in class and it becomes a requirement to go to office hours just to figure out how to start the homeworks. He gave out an extra credit assignment in the end(did not drop any other assignments). The exams were also very fair.
Mohammad Nayeem Teli CMSC250 Expecting a B- Anonymous 12/23/2022	Teli is not a bad professor himself, he's actually very straight forward in lectures sometimes. I do think at the start though, he did go a bit fast, but he's understanding when it comes to answering questions and office hours. However, his quizzes and exams are in my opinion a gamble, sometimes they are easy/fair, meaning it is the content taught in class but other times he has completely given us a homework and quiz that is entirely different from his lectures. At one point, lots of people crowded office hours because there were so many questions on this one homework. It definitely was inconsistent. As well, you have a quiz every week in-person unless stated otherwise, and as stated before, some were straight forward and others were completely different from what we learnt. The platforms being used are a bit annoying to, having to use Piazza, ELMS, and a whole different website (for the syllabus) is a bit disorganized. I also do want to mention that the grading felt very inconsistent on exams, so try your best to get a regrade request (for a valid reason of course).
Cliff Bakalian CMSC250 Expecting an A Anonymous 12/22/2022	His TAs are inconsistent with grading. There have been multiple instances where my answer is basically the same as my friends but I get less points. I emailed Cliff for a regrade because it was impossible to get one done over gradescope (the TA wasn't taking my argument) and he never got back to me. The only reason I might get an A is because you get 10 extra points for using Latex on your homeworks, and two of them get dropped. I like his late tokens policy, even though I've never used them. I know it would have been nice to have that for some of my other classes. Cliff sometimes gets confused during his lectures, but it's understandable since he's not as experienced as other lecturers. Other than that, he did a pretty decent job of explaining the concepts. His TA took over one of his lectures, though, and I think she was a lot better.
Mohammad Nayeem Teli CMSC250 Expecting an A+ Anonymous 12/21/2022	His quizzes and tests are very fair, which is very nice. Homeworks are also relatively straightforward - very closely mirrors what is done in class. Unfortunately, CMSC250 as a course is sort of this weird Frankenstein of a math class trying to be taught to CS kids that don't really care about math, so the material is a bit weirdly presented, but that is by no means his fault. My biggest takeaway, though, was that he really really cares about people doing well, and is super accommodating. Someone asked he post the lecture slides before class, so he did just that. He gave an optional extra credit assignment at the end. Great dude.
Paul Kline CMSC250 Expecting an A- Anonymous 12/21/2022	As a side note, Kline first co-taught this course with Cliff Bakalian, who has his own set of issues, so I'll cut him some slack. As a lecturer, Kline is great. It's clear that he's very enthusiastic about teaching the course material. HIs style is teaching by example, which is really beneficial for a class that is oriented around proofs and intuition. In terms of the structure of the course, there are some issues. The homework was pretty awful and—for students who tend to have a slow start adjusting to course material—overwhelming. It didn't help that the grading of homework was incredibly delayed either. Additionally, out of the three exams that we had (including the final), only ONE practice exam was posted (and based on the grade distributions for each exam, the one with the practice exam is the one people did the best on). Regardless, several of these issues can be attributed to being a new lecturer at UMD and not having complete authority of his course, so I think he'll be a better option for incoming CS students in the future.
Mohammad Nayeem Teli CMSC250 Expecting a B- Anonymous 12/20/2022	You know, I didn't really pay attention in lecture but I somehow still learned by osmosis anyway. Very nice guy, I like his lectures even though I just fuck around or skip it altogether. The course material is pretty good, the homework is really good practice. The quizzes are a bit weirdly timed to the homework, where you might get quizzed on something before you get homework about it. Otherwise, he's really nice, and very solid. The only real problem I would say is that the final exam turned out to be exam 3, not really a final exam. But hey, whatever.
Mohammad Nayeem Teli CMSC250 Expecting a B Anonymous 12/20/2022	Teli is a good professor, but CMSC250 is definitely a difficult class. Attending lectures will fs help you. Plus, he records them so you can review for any times you missed or to prepare for exams. Discrete is different than a typical math class in that it's more proof and logic heavy, so expect a fair bit a writing as well. Also, if you have Emily as your TA, she is AMAZING. She's a god-send and helps explain topics so well during office hours to help students with the homework, and she also hosts review sessions before finals. I HEAVILY suggest her as a TA for the course.
Paul Kline CMSC250 Expecting a B+ Anonymous 12/19/2022	Paul is a solid lecturer and was very fair throughout the entire course. I'm not going to dock him stars here for the organizational problems that cliff's class has because I mainly attribute those problems to Cliff.
Mohammad Nayeem Teli CMSC250 Expecting a B+ Anonymous 12/19/2022	Lectures are clear and organized and he always posts the recording and notes. Exams were always more than fair. Quizzes and Homeworks were a bit difficult but if you study a bit you'll be fine. Pretty solid professor if not a little boring at times.
Mohammad Nayeem Teli CMSC250 Expecting an A Anonymous 12/18/2022	Explains things in an easy to understand way and gives us a lot of practice material.
Paul Kline CMSC250 Expecting an A- Anonymous 12/17/2022	Kind of a nerdy, chill guy. Good lecturer, moves his class at a reasonable pace. Homework is challenging, but they're designed to be that way because they have significantly harder questions than you will ever see on an exam or quiz. There are 4 online quizzes during the semester designed to take 2 hours each, which is a bit excessive but they're typically doable. Exams are very fair, there was one section on exam 1 that most people did horrendously on and he offered a makeup assignment to get points back. Final exam was also very fair. He currently co-teaches with Cliff so the class is definitely a bit disorganized, but show up to lectures and discussions and this is a very doable class.
Daeun Jung CMSC250 Expecting an A- Anonymous 12/17/2022	One the kindest and best TAs out there. Very thorough with her explanations.
Mohammad Nayeem Teli CMSC250 Expecting a B- Anonymous 12/17/2022	i actually think he's an very underrated professor. although his class was a bit disorganized, he did a great job in making things make sense. Really nice dude, and I genuinely enjoyed this class even though it was hard at times.
Cliff Bakalian CMSC250 Expecting an A- Anonymous 12/17/2022	Decent choice overall. Lectures can be a bit dry but the TA's are very helpful. Exams were pretty easy and fair
Cliff Bakalian CMSC250 Expecting a B Anonymous 12/16/2022	Pros: - Slides are very detailed and easy to read - Goes through many examples when explaining concepts - Exams reflect content covered in lectures - Offers extra credit Cons: - Doesn't post lecture recordings
Mohammad Nayeem Teli CMSC250 Expecting a B+ Anonymous 12/16/2022	take him
Mohammad Nayeem Teli CMSC250 Expecting a B Anonymous 12/14/2022	Solid professor. Taught what needed to be taught, was very nice. Everything you'd want out of a professor. Homework could be a bit hard, but are fair. Quizzes and exams were totally fair so long as you studied the material. Plus he posts the lectures and slides, and gave us an extra-credit assignment after someone asked for one!
Paul Kline CMSC250 Anonymous 12/14/2022	Great professor, not a very good course. Discrete Structures is a challenging course. In my honest opinion, Paul does a decent job at teaching the material. He is a nice guy who is interested in the things that he's teaching. He also knew that a part of an exam was hard, so he did a supplement assignment to the exam on the part that was hard. One of my concerns is that (like others have said) he co-teaches and is not in full control of his content. He is also a first-time 250 teacher (which is why I'm more lenient on his rating). Also, his slides are not as interesting as what I've seen with Cliff. Sometimes I get lost and I don't know where we left off. Overall, I hope that this semester will help him see the waters of teaching so that in the future, he will be one of the best lecturers.
Cliff Bakalian CMSC250 Expecting a B- Anonymous 12/10/2022	I would stay away if possible. His class management is very poor and his teaching is horrible. He over complicates everything and makes stuff harder to understand than it needs to be. However, his exams are very fair.
Paul Kline CMSC250 Expecting an A+ Anonymous 12/10/2022	It's obvious that Paul enjoys the material he teaches in a nerdy way. He made great efforts throughout the semester to engage us with discrete math and generally explained concepts very well. The exams and quizzes in this class were also generally very fair, closely matching the course content and what we had seen before in homework questions. However, mostly due to the fact that this course was co-taught with Cliff Bakalian, there were still some structural issues. My main problem was that the instructors didn't reference any textbook throughout the course - this probably fine for any other 100- or 200-level CMSC class, but in a largely proof-based math course it meant that the sole authorities for clarifying concepts were the slides (often with typos or with information omitted because they were good slides for presentation but not for reference) and the provided style guide (updated throughout the semester but not consistently). It would have been nice to have more consistent resources to refer to throughout the course instead of having to reference Stack Exchange or Proof Wiki for some homework questions that were not adequately given context in lecture.
Emily Kaplitz CMSC250 Expecting a B Anonymous 12/10/2022	OMG The best TA ever. She is so helpful and you can tell she would do everything for her students to be successful + she's funny and so nice. I loved taking a class with her. 100% WOULD RECOMMEND
Mohammad Nayeem Teli CMSC250 Expecting a B Anonymous 12/08/2022	Prof. Teli is a solid professor. He goes over examples clearly in class, gets his TAs to grade homeworks and quizzes relatively quickly, and the material tested is fair game. Make sure you prepare for, complete, and understand your weekly homeworks and quizzes on time. Sometimes he can go too fast for you to take notes, but he always posts his lectures and lecture notes immediately after class.
Emily Kaplitz CMSC250 Expecting a B Anonymous 12/03/2022	CLAIM: Emily is the absolute best teacher ever. PROOF by contradiction: First, we will assume Emily is not the absolute best teacher ever. Emily breaks down concepts and explains them very clearly. It's obvious she goes above and beyond to make sure every student can do the best that they can. Despite being a busy grad student herself, she is always very consistent, gives us feedback quickly, responds to emails, and more. Moreover, I can definitely tell she deeply cares about the success of her students, thus, proving a contradiction. I highly recommend everyone to totally, definitely, absolutely take her. QED
Cliff Bakalian CMSC250 Expecting an A- Anonymous 12/01/2022	Cliff is an alright choice for 250. He's not amazing at explaining new concepts but not terrible either. Tests were pretty easy, though, especially when compared to the homeworks. Not a bad choice by any means.
Paul Kline CMSC250 Expecting a B Agt 11/30/2022	It's important to keep in mind that Paul's first semester teaching CMSC250 was for a class shared with Cliff Bakalian, so his class inherited much of the same, notorious issues that Cliff is known for (frequent grading discrepancies, disorganized structure, delayed feedback on submitted work, inconsistent expectations, etc.). However, Paul lectures are solid and always conveniently recorded online. He will provide generous accommodations to students who need them, and engages with the class on a frequent basis. I can see him becoming a solid lecturer for CMSC250 once he has full charge of his own class.
Mohammad Nayeem Teli CMSC250 Expecting a B Anonymous 11/23/2022	Telli is a great professor: - Comes to class with a ton of energy, - Always willing to help and spend an hour if need be to clarify - Quizzes aren't bad actually, rules of inference/proofs is the only thing I should've doubled down on - Tests: are hit and miss but overall, I'd say they are decent and cover everything equally - HW: In the beginning of the year, very long and tedious but later in the year, dirt easy. - TAs: Mine was ok, but definitely be sure to learn his/her style. - Teaching: Good pace, lots of explaining, and writes the notes in real time so you can see the mechanics. Overall, Telli is an amazing professor with a great heart. I am taking him again in CMSC 320. He is a professor you want to stick around with. I hope this review helps! Harshit Garg
Mohammad Nayeem Teli CMSC250 Expecting a C+ Anonymous 11/22/2022	Nice professor. Lecture is pretty nice, but can get boring at times. Harsh grading, though.
Mohammad Nayeem Teli CMSC250 Expecting a B Anonymous 11/15/2022	Nice guy, explains every concept and topic really well. Exams and quizzes can be tricky, and the homeworks are graded extremely harshly for some reason. My main pitfall is that he's not super great with responding to emails or anything like that, took him almost a week to respond to my email about rescheduling an exam I had to miss due to COVID. Otherwise pretty good professor!
Emily Kaplitz CMSC250 Expecting a B TheAscian 09/29/2022	The best professor/TA to learn 250 from next to Justin. If you see Emily teaching 250 I encourage you to take it with her. She is a godsent for this class! She makes sure you understand the topic and does a fair amount of examples. Also please attended the review session around exam time they are so helpful and can clear any problems you are having. There sure be more positive reviews for how good she teaches. Overall if she is teaching or being a TA go to her!!!! Also talk to her about Nintendo things especially Pokémon makes for good conversation.
Emily Kaplitz CMSC250 Expecting a B Anonymous 09/29/2022	I had Emily during the summer 2022 after completely failing 250 in the spring with Cliff. His teaching style just was not for me. But Emily she is godsent idk why there isn't more reviews for her . She clearly explains the topic in depth and does several examples to make sure you are ready to do the homework. Around exam time she does have a review session with practice problems I encourage you to go to them! Overall she is the best professor for 250 because she does not try to trick you at all and makes sure you understand the topics. Side note talk to her about anything Nintendo related especially Pokémon you'll have a blast having a conversion with her.
Daeun Jung CMSC250 whiskers 09/08/2022	dude, i cannot understand what shes saying, and ive been around thick asian accents for my whole life. she does write on the board in a very explanatory way but she erases what shes written after like 10 seconds. would avoid
Cliff Bakalian CMSC250 Expecting an A- Anonymous 05/28/2022	To do well in this course, study Justin's notes. For quizzes and exams, showing how you got the answer is important and you will lose points. However, Cliff doesn't teach how to do it, he just scribbles all over the board leaving the class confused. His class is manageable, but I would rather take it with someone who grades harder and teaches better.
Cliff Bakalian CMSC250 Anonymous 05/20/2022	really bad organization of the class
Cliff Bakalian CMSC250 Expecting a B- Anonymous 05/20/2022	Just gonna say, this class was so rigged and I'm so glad I'm out of the woods. Most people cheat and screw others over by making the exams have an unusually high average. Cliff is nice but also delusional when it comes to this issue. It was survival of the fittest/"get a high grade by any means possible" all semester long. The exam reviews were not that helpful and were recycled from last semester. Additionally, we were given wrong answers for them. I felt like two of the TA's at office hours took more of the role of professor than Cliff did in lecture. Can't even read his hand writing because he uses a super pixelated drawing program. He also took out learning about logic circuits from the class which really sucks considering this is a computer science course it'd be nice to know about those. Just be prepped to be at office hours regularly and maybe you'll do okay.
Mohammad Nayeem Teli CMSC250 Anonymous 05/18/2022	While very knowledgeable about the topics the class was pretty bad. Quizzes had random content at times but exams were ok. Try to avoid taking him if you can.
Cliff Bakalian CMSC250 Anonymous 05/18/2022	People are correct about his disorganized class, but I think he still is a great prof to take. All exams and quizzes were online which was nice, and the overall was just a great and accommodating person. His lectures were tough to understand at times as his handwriting is pretty horrible. If he continues to keep the content online take him, if not then run.
Cliff Bakalian CMSC250 Anonymous 05/17/2022	I think some of the bad reviews that he is getting on here are a bit unfair (especially the comment about his speech impediment) considering how accommodating he was to students this semester. He made all quizzes and exams online, moved multiple quizzes because of upcoming exams in other courses, and was generous in providing make-ups. Also after students complained about it taking too much time to take the first exam, he made the second exam and final shorter and easier. Grade averages this semester were pretty high for this semester, so not much of a curve will be needed. For the most part his lectures went at a decent, if not a tad slow, pace. However, there were certainly some issues in the structure of this course. Grades took a very long time to come out for many assignments, and many times the TA's made mistakes in grading. But they were all rectified with regrade requests. Overall, I do think that taking this course with Cliff is a good experience, and I thought that all-around he was a very solid professor. There is no doubt that he truly cares about his students and wants them to succeed in his class. His luscious locks make attending lecture worth your while.
Cliff Bakalian CMSC250 Anonymous 05/17/2022	Cliff is a great person and a decent teacher. He is definitely understanding of students' concerns and I feel that he teaches the material in the course properly (wish Cliff was more engaging though and enthusiastic). However, I think his management of the class was rather poor. Assignments were never graded correctly and very few TAs seemed to care about teaching the course material properly. There would be several times when a student had the correct answer and approach to solving a problem but would get graded incorrectly. I think that through better management and more enthusiasm for the content, Cliff could easily become a great professor. He is young and has a lot of time to improve. Hopefully, the class will go much better next sem.
Cliff Bakalian CMSC250 Expecting a B Anonymous 05/16/2022	Pros: The class was entirely online and open note this semester so was not particularly difficult (stress load/work wise). His exams are more or less fair although a bit of a time crunch. Cons: This man is a genius in everything EXCEPT teaching. His lectures are straight from Justin’s Notes (which carried me through the course), but the way he explains everything so disinterestedly makes them so hard to watch. Plus, the examples he provides in lecture are not well explained and incomplete. Honestly I ended up just using Justin’s notes for most of the class and the only reason I watched his lectures were to make sure I was using the style he wanted for proofs. However, there was no point as he is EXTREMELY inconsistent in grading. I don’t know if it’s him or his TAs. He goes back in what he says about style numerous times and the only reason I’m even finishing with a B is the amount of regrade requests I submitted. Overall, the only positive about taking Cliff this semester compared to the other professor is that his class was online. I feel bad for whoever has him in coming semesters in person. I honestly don’t know how I would pass the class with his terrible teaching and inconsistent grading .
Cliff Bakalian CMSC250 Expecting a B+ Anonymous 05/16/2022	I took Cliff in the Spring of 2022, and I probably have a totally different experience than everyone else. Cliff was a super flexible guy who cared a lot about his students, and he did try to set us up for success. I believe the downfall of the course was the disorganization and laziness of most TAs throughout the semester as the grading had a lot of errors for people with it being inconsistent as well (since everything was online). There were a lot of errors on assignments as well, which I hope Cliff is more cautious of next semester. However, i never really got affected by any of this and I really did enjoy and felt like I learned a lot in this class. Cliff offered tons of OH, and I know some cannot make it to OH, but i found it to be super helpful I could come anytime to OH whenever I had a question, and I would say all the in person TAs were super helpful this semester over the ones online. I will stand by my 5 star rating because I thoroughly enjoyed the class, I never had anything wrong happen for me, and Cliff (and all In person TAs) were super helpful to me this semester to learn discrete math. If you are willing to just get out of your bubble and try to use the resources Cliff gives you to the best of your ability, the class isnt too bad. Some materials that really helped me in the class was: The lecture slides, IN PERSON OH, Justins Notes, the recommended textbook, discussion slides and recordings from some TAs, and answer keys for every single assignment despite the errors. I think Cliff will do a better job next semester and will eventually shape how he wants to structure his class in an organized manner soon.
Cliff Bakalian CMSC250 Expecting an A- Anonymous 05/16/2022	Solid guy, seems pretty chill. However, his teaching and course organization abilities are frankly dismal. Most assignments have errors in them, adding to that there would be grading mistakes for almost everything. Lectures are boring and hard to follow. The pacing of the material is extremely poor, with some lectures covering seemingly nothing important and others leaving many students confused. The worst part of the class, however, are the TAs. It is obvious that the TAs don't care about the class whatsoever, the discussions are poorly led and the TAs often give contradictory information. To do well in the class, students are forced to constantly haggle for points on blatantly ignorant grading. The material should be easy to understand but being in Cliff's section made this class far more stressful and difficult than it had any right to be. The silver lining is that Cliff is a new teacher and should learn from his mistakes as he gets more experienced, oh, and he has cool hair... I guess.
Cliff Bakalian CMSC250 Expecting a B Anonymous 05/16/2022	Immaculate hair, but his TAs are quite disorganized and grade inconsistently from each other. His handwriting Isnt stellar so you have to pay extra attention to what he is saying and his lecturea overall arent too good for note taking since its almost all just examples, each being implement in a different manner. Regrades take ages and the autograder has had mistakes in almost every homework, 8/11 if im counting correctly.
Cliff Bakalian CMSC250 Expecting an A Anonymous 05/16/2022	CMSC250 with Cliff started off very well, but it ended with some noticeable flaws. This may be due to lack of teaching experience, miscommunication with the TAs, or some TAs slacking on their share of grading work. But PLEASE NOTE, I'm not considering class management in this review. Homework grading took a considerable amount of time, and there were often incorrect problems/solutions in exam practice problems. Whether this was Cliff's fault or the TA's, this was a major issue that stressed out many students and must be taken care of for future classes. Considering lectures, I thought Cliff was a solid instructor. Sure, some content could have been explained better, but Cliff made an effort and answered every question during or after lecture. I think the best way to prepare is to read Justin's 250 notes alongside regularly attending lecture. Other than doing the homework (yourself!), you should understand the general content. To me, lectures felt well paced and taught. Some content was boring, but well, it's 250. Just attend lectures and take notes and do your share of studying and you'll be fine. Exams were fair. Quizzes were fair. Got extra credit opportunities sometimes. Like others have said, Cliff is one of the most understanding instructors. If you approach him and explain your situation, he will accommodate. Super nice and chill guy. I genuinely think that in a few years Cliff will be a top-tier instructor. Hopefully 250 will not have these issues with grading/TAs moving forward. Side note: Cliff might keep exams/quizzes online moving forward. Don't cheat with others. Not worth the risk and 250 content is important in later courses. You'll get imposter syndrome if you do.
Mohammad Nayeem Teli CMSC250 Expecting a C+ Anonymous 05/16/2022	Teli is strange. At the beginning of the semester, it seemed like he was a great professor, and that he and Cliff were keeping pace. However, it just got worse from there. The difficulty, quality, and wording of his assignments vary wildly (both in between assignments of the same type and assignments of different types). This made it extremely difficult to productively study for exams and quizzes because I'd never be quite sure how they would flow. Teli also fragments course information across 4 different platforms (ELMS, Piazza, Gradescope, and his own UMD web space), and not all of these platforms send notifications. For the platforms that do send notifications, it is so hard to keep track of them and I have felt like I'll receive them a long time from when they were relevant (I have definitely missed a regrade window because of this fact). Finally, the TAs all had their own slightly different ways of doing things and interpretation of assignments, which I can only assume comes from lack of communication. This made grading inconsistent with different rules being applied to different assignments. TLDR: Do not take CMSC250 with Teli unless it is your only choice.
Cliff Bakalian CMSC250 Expecting an A- Anonymous 05/15/2022	Cliff's 250 this semester was quite an experience that could (and should) have been much smoother. As already mentioned, his biggest flaws are much mismanagement (having no work graded until 1 week before the final, including the second exam, very little explanation as to why points are taken off and what is expected, hardly responding to emails). A decent portion of my grade lost would be from assignments that I was not able to send or resend in time from not having a printer which stifled numerous questions on quizzes and exams. Additionally, there were some times when he muddled up material, or said things incorrectly and didn't follow a set standard that TAs may have graded. However, given that Cliff is a relatively new professor, and was handling 2 huge CS courses this semester, it seemed he did try to put a good deal of effort in both courses. In addition, the hybrid structure of in person lectures and exams/quizzes being online was weird to adapt to and caused numerous issues, which is not Cliff's fault particularly. He definitely has a chance to grow and despite the problems, he did an alright job handling the teaching/lecturing he needed to do this semester.
Cliff Bakalian CMSC250 Anonymous 05/15/2022	This class had the potential to be good. Cliff structured the course in a "hybrid" kind of way that was very understanding towards students—lectures were-in person but basically everything else was online and/or asynchronous. Homeworks were encouraged to be done collaboratively; quizzes and tests were open-note. Lectures are dull but not notably duller than any other 3-star CS professor I've had so far. Incredibly poor organization, however. Slow and inconsistent grading. Takes off points for style yet the lecture examples—Cliff handwrites proofs and screen shares—are a mess. I stopped showing up to discussion because my TA didn't seem to care about the content, and because what we were told in discussion didn't always line up with what we were told in lecture and/or what was expected on graded assignments. The proof style guide was helpful but only for the first few units, and then it was no longer maintained. Most of my learning in this course came from provided practice material, which was okay in the beginning but once we started getting to more word problems—proofs, statistics, combinatorics, etc.—hilariously poor quality. Hilarious because if someone just proofread the material once, 90% of the problems could be fixed. They're obviously copied and pasted from other sources—they'll be talking about pizzas one sentence and party hats the next, which isn't so bad until you try to check your work and they didn't even bother to change the answer key to match the new question at all. Answer keys are wrong or just plain irrelevant on a good chunk of the questions. Unclear phrasing and the questions can be interpreted many ways, which isn't great when they're expecting one solution. Ask three different people these questions and they're bound to interpret the question three different ways. I only grasped the combinatorics and statistics unit because of Justin's notes and through group studying in order to figure out what the question is really asking.
Cliff Bakalian CMSC250 Expecting an A- Anonymous 05/14/2022	Lectures might be a bit boring but all of the content you need to know for the exams is explained pretty well. Quizzes and tests were online and open-note for us which made them very stress-free.
Cliff Bakalian CMSC250 Expecting an A Anonymous 05/12/2022	Very disorganized class, grading was extremely poor, examples were convoluted, and it seemed that there was no consistent standard for how proofs should be written, as Cliff seemed to change his style at random between lectures. Would definitely recommend avoiding Cliff.
Cliff Bakalian CMSC250 Anonymous 05/11/2022	While there were a few snags this semester, Cliff clearly cares about the class and is doing his best for his first-time teaching independently. At most, the late turnaround on assignments and errors in grading were inconveniences, and did not impact my understanding of the class at all. His lecturing style worked for me, and I always felt set up to complete all the assignments just from just the lectures. Most of all, Cliff is simply the most compassionate and understanding professor I've ever had. People here put that in as an aside, but if some roadblock suddenly emerges mid-semester, you will be very glad to have Cliff instead of a more apathetic professor. Overall, I think it is only fair that we give Cliff the same level of compassion that he extends to us. Given that it's his first time alone and he's clearly trying his best, I'm willing to let a few things slide.
Mohammad Nayeem Teli CMSC250 Expecting an A Anonymous 05/09/2022	Teli is a terrible professor. He doesn't teach us anything and the quizzes/HWs don't match up to what we're learning at all. However, I must concede that he is experienced and knows the content. The exams were also rather reasonable. Only take Teli if you have to. And if you do end up taking him, buckle up.
Cliff Bakalian CMSC250 Expecting a C- Justacoder 05/09/2022	TLDR: Nice dude, poor teacher Look I want to be fair. Cliff is a nice person and I feel like he understands what we go through. With that said I really felt hopeless at time during his class. I didn't really understand these concepts until I started reading Justin's notes. (I guess that's sort of my fault, if I had looked at the notes earlier maybe I would have done better) His lectures honestly jumped around a lot. When showing us steps he would sort of pull out solution from thin air. He didn't show us the intuition and the though process behind what he was doing. This lack of clear steps really frustrated me. Grading wasn't great. His examples in lecture don't go into enough details and so on exams and quiz's I would miss several points because of formatting or slightly different methods. The grading was also inconsistent at times. Several regrade request were sent.
Cliff Bakalian CMSC250 Expecting a B+ Anonymous 05/08/2022	Cliff is nice and understanding but his teaching style is very subpar. He's constantly unorganized and doesn't respond to emails. Although he records lectures to post online, he is constantly late and posts the material needed for homework on the day it's due. It seems he doesn't understand how to take responsibility and maybe that's because this is his first class he is teaching without help, but over the course of the semester, I started to realize that he continues to fall below normal standards.
Cliff Bakalian CMSC250 Expecting a B+ Anonymous 05/07/2022	Great person, horrible teacher. Every single paper or lecture has has a mistake, even answer keys and en exam. Don’t expect to get scores back for anything until 2 months after you submitted it. Cliff doesn’t look at Piazza doesn’t post lecture videos until weeks after you need it. Terribly run class but I believe he has potential ti be great, just not anytime soon.
Cliff Bakalian CMSC250 Expecting an A- Anonymous 05/07/2022	immaculate hair but terrible class management
Cliff Bakalian CMSC250 Anonymous 05/07/2022	Cliff's class is the most awfully organized class I have every taken. Nothing is posted on time: lectures, grades, etc. Good person, but highly overrated as an instructor because he co-taught with Justin. All of his content is recycled from Justin's material, and it doesn't even feel worth going to lecture. His practice exam for the final consists of a copy paste of the Exam 1 and Exam 2 practice exams, with like two additional questions, even when he stated that over half the final would be on stuff after Exam 1 and Exam 2. Probably because this was all the content available from Justin. It's overall a horrible experience to constantly be frustrated with nothing being graded properly, posted on time, having no idea what your grade is, and feeling like you aren't set up to succeed in the class. I would not recommend taking Cliff if there is a better alternative.
Cliff Bakalian CMSC250 Expecting a B+ Anonymous 05/06/2022	Honestly has the potential to be a great teacher but is completely unorganized and seems like he doesn't care. Grades for assignments are not released until 2 months later which does not help you for exams or homework at all.
Cliff Bakalian CMSC250 Expecting an A Anonymous 05/06/2022	Maybe the material just came quickly to me, but the organization of this class was a mess. I understand Cliff is young and stressed and new to teaching, but oh my Took about 2 months to get an exam graded, multiple questions were messed up. I am not joking when every single assignment/homework/quiz/exam he gave us had some sort of mistake on it. I have never seen a group of TA's who have cared less about what they're doing, and honestly, it was extremely insulting. Every single homework had an issue with grading, as well as quizzes and exams. I understand that this isn't Cliff's fault, but it felt like my future in CS was being determined by his TA's who must've had their eyes closed while grading any assignment. It honestly felt like the entire team gave up halfway through. With all that being said - He understands what he's doing. My guess is that he just needs time - AND NEW TA'S.
Cliff Bakalian CMSC250 Expecting a C- Anonymous 05/06/2022	Don't take him. Period.
Cliff Bakalian CMSC250 Expecting a B- Anonymous 05/06/2022	DO NOT TAKE CLIFF!!!! Confuses himself in lectures, illegible handwriting, speedruns lecture slides in monotone, doesnt post lecture slides for weeks, takes 3 MONTHS to grade EACH homework, and once it is graded there are mistakes everywhere with autograding and TAs. The previous ratings were when he co-taught with Justin so he had high ratings, but now that he is on his own, he is beyond awful. Perhaps the worst class and lecturer I ever had. If you are fine with not having half your homework, quizzes, and exams graded when you take your final exam and are fine with a disorganized monotone speedrunning professor with illegible handwriting then take this course.
Cliff Bakalian CMSC250 Anonymous 05/06/2022	Cliff has good intentions but is far from being a good, or even an average instructor. This was his first semester teaching and the class has been a disaster. Mistakes on every assignment, weeks to grade, slow responses - overall a really frustrating experience. His class was the worst organized class I have ever taken.
Cliff Bakalian CMSC250 Expecting a B Anonymous 05/05/2022	Cliff doesn't know the material he is teaching and recommends us to use Justin's notes because he even confuses himself during lecture. He didn't post lectures until weeks after the material was covered in class and in those videos, usually posted after the homeworks were due for that material, he would correct himself about something he said during the in person lecture. He didn't hold his TAs to any standard and he was very behind in grading and we had to go into every quiz and exam without knowing the grades of the relevant work we turned in weeks prior. He told us at the start that he came from a philosophical background and not CS and it showed. He would trip up on his wording and sometimes would scrap half of the work he was writing because he was lost himself. I would try to avoid him in future years if he ends up teaching anything more than 250 because I can't deal with being taught by someone who acts like a student themselves and can't stay on top of their own responsibilities. I know this was his first semester teaching on his own but it was even worse than I thought it could have went.
Cliff Bakalian CMSC250 Expecting a B Anonymous 05/04/2022	Great guy, terrible teacher. Cliff cares about his students, but the structure of the class and lectures was god-awful. There was seemingly little communication between him and the TAs, leading to a lot of misunderstandings and extremely delayed grading. Lectures were either incredibly trivial and boring or very confusing. Lectures also often didn't prepare us fully for the homework or exams. The grading was super questionable for everything, and almost everyone I talked to in the class submitted multiple regrade requests throughout the semester. Mistakes on seemingly every homework assignment were only fixed several days after being released. I actually learned most of the content in Discussion thanks to my GOAT TA. Cliff bases his lectures and content off of Justin's notes, but often presents them in a more confusing manner. The previous positive reviews were from when he co-taught the course with Justin, so I guess it was drastically different than this semester, because the general consensus is that this class was a mess.
Cliff Bakalian CMSC250 Expecting an A Anonymous 04/29/2022	Cliff is a very understanding person, but he has very boring lectures, keeping me and others very disengaged. Handwriting is not good so it’s hard to follow, and when it comes to grading, there will either be a lot of mistakes or grades just won’t come out until a month after the assignment.
Cliff Bakalian CMSC250 Anonymous 04/28/2022	Very boring and unorganized teacher. Don't expect anything graded for weeks.
Mohammad Nayeem Teli CMSC250 Expecting a B+ Anonymous 04/28/2022	The best I can say about Teli is that he is a good guy and he really cares about his students. However, this is only the second time that he has taught 250 and it really shows. His course materials are at least half a decade old focusing on subjects none of the other 250 teachers teach anymore. Additionally, notes and materials from other teachers are useless since he sometimes just makes up his own proofs. Teli also doesn't provide any detailed notes or practice exam materials which is very frustrating. His lectures are difficult to follow skipping essential material and making substantial mistakes in all of his example problems. The worst part is that his test, quizzes, and homework are extremely difficult and is completely different from anything he teaches in class. His grading is brutal and the TA often grades incorrectly so it's important to request regrades. Overall, I hope Teli gets better as he gains more experience teaching this class, but I cannot recommend taking CMSC250 with Teli at this time.
Cliff Bakalian CMSC250 Expecting an A Anonymous 04/25/2022	Not very engaging as a teacher but gets the job done. Handwriting isn't the best so sometimes it's hard to follow, and examples in class aren't nearly as hard as the homework/exam questions. Class is unorganized as a whole, as documents and solutions always seem to have some typo or mistake. TA's are not that helpful and sometimes can't answer certain questions. Grading is very poor, as graders often make mistakes when grading and it takes very long for assignments to be graded. Regrade requests aren't looked at for a long time as well. Cliff is an understanding and nice guy, who keeps the students' best interests in mind, but there are definitely many things that can be improved.
Cliff Bakalian CMSC250 Expecting an A- Anonymous 04/25/2022	Hard HWS but can do with friends. Generous to students about quizzes and exams. Lectures start off slow, but speed up. Never got too fast tho.

Jason Filippou CMSC250 Expecting an A- Anonymous 03/31/2022	Cringe professor. Tries too hard to be funny; has pointlessly stupid questions for quizzes that don't make any sense (i.e. one time there was an answer choice that says "Proof by Human Exahustion"), and for multiple choice questions you have to pick exactly all the write options and none of the incorrect options, or you will lose all points for said question, which makes no logical sense for someone who claims to be a "logician". Another time he said you have to answer 0 instead of "63 choose 64", even though they both equal 0 and are technically correct, simply because "63 choose 64" doesn't demostrate cRiTicAL tHinKInG. Choose him if you want to cringe for a semester.

Justin Wyss-Gallifent CMSC250 Expecting a B Anonymous 12/22/2021	Fantastic lecturer, makes concepts easy to understand and apply. His notes on his website are a life saver and are remarkably thorough. His exams were fair and straightforward if you were prepared, and the homework problems were extremely relevant to the exams. Greatly enjoyed taking this class with JWG; even if math is not quite your thing, pay attention and do the homework and you'll succeed. Highly recommend.
Cliff Bakalian CMSC250 Anonymous 12/22/2021	First of all, his hair is amazing. Second, he is a really nice guy and he wants you to succeed. The co-taught with Justin WG this semester, and the exams were reasonable. Some of the homeworks were pretty difficult, but they are not impossible if you utilize office hours. I would recommend him!
Justin Wyss-Gallifent CMSC250 Expecting an A Anonymous 12/18/2021	Great lecturer, hard to pay attention at times with the 75 minute lectures but that's a personal problem. Only thing I can complain about is the absolutely atrocious organization of the course. Every released practice has at least 13 mistakes on the answer key, 50% of my homework had to be regraded because the TAs misread and marked my answers as incorrect when they were correct. Overall, probably one of the best lecturers out there but not great at organizing courses.
Justin Wyss-Gallifent CMSC250 Expecting a B- mewuzhere 12/16/2021	This probably doesn't need to be written again but Justin is one of the best at UMD. If you have the opportunity to take him, take him. Lectures were engaging and super organized. He provided all of the notes that he used for lectures. Exam expectations were very clear. Homework tracked well with the material in the lectures and was helped reinforce concepts. Everything was graded in a timely manner and everything was well communicated.
Cliff Bakalian CMSC250 Anonymous 12/09/2021	Cliff teaches really well. He's young and relatable, his lectures are organized, and he does a great job of answering questions and clarifying on points of confusion. He seems like a nice person too. My only qualm would be with the class itself, which was that the homeworks often covered really complicated or difficult applications of what was covered during the lectures, especially towards the end of the semester.
Justin Wyss-Gallifent CMSC250 Expecting an A fiftyseven 12/09/2021	Amazing teacher. Super engaging and explains everything really well. He handles any student questions really well too, not only answering them but going into depth so everyone gets a better understanding. Uploads the notes for the class so you can see everything and review it. In addition, he has his own typed up LaTeX notes he uploads which are also really good. Workload is good too, just a weekly assignment. Would highly recommend.

You learn a lot and you get to practice weekly with homework and quiz to solidify your knowledge. Sadly, I don't think Jason will be back to teach again.
Jason Filippou CMSC250 Expecting an A- Anonymous 05/26/2021	Jason's a really good professor. Yes the class is difficult, but that's to be expected. If you're having trouble with concepts, talk to Jason or the TAs in office hours. Jason's easy to talk to and he always keep it real. He also released additional videos outside of lecture to help us understand concepts that we're struggling to pick up. In short Jason really did everything he could to ensure we had a smooth semester. Also quick shout-out to the TAs. They were all phenomenal.
Jason Filippou CMSC250 Expecting a B- Anonymous 05/25/2021	Difficult course, prepare to be challenged a lot. If you don't understand a concept fully, ask questions. If something doesn't click for you properly, it will not go well for you on exams. Jason is a fine teacher. He explains everything well though at times it can get a little bit confusing and wordy, discussions and homework were also really helpful to fully understand concepts. Jason tries to relate to his students a lot and he's sort of like the elder brother you never had. He definitely keeps it real with his students.
Jason Filippou CMSC250 Expecting an A- Anonymous 05/25/2021	Extremely well recommended. The course was difficult, and I definitely could have done so much better in the class in hindsight, but Jason did extremely well explaining concepts and taking time out to go through student questions and concerns and address them to the best of his ability. He and the TAs did an extremely good job helping us as students and doing their best to provide us a better experience in the course. Exams and quizzes were graded on time, we had a 24-hour window to submit exams which was extremely helpful, we had recordings of lectures and lecture slides available to us, and Jason created a spreadsheet complete with resources, discussion links, relevant textbook sections, etc. All in all, I had a pleasant experience with the course, and would recommend taking Jason as a professor. :)
Jason Filippou CMSC250 Expecting a B- Anonymous 05/25/2021	Pretty difficult course overall, but Jason explains things pretty well and is very receptive to student concerns. TAs are also awesome for this class. Exams are also very fair and were pretty generous, including a 24 hour submission window.
Jason Filippou CMSC250 Expecting an A- Anonymous 05/16/2021	One of my favorite professors now. The class is difficult and I definitely could have done better on the exams, but Jason explains everything so well. He and his TAs were always quick to respond to student concerns, and he made adjustments to the syllabus throughout the weeks to better accommodate everyone. He's easy to communicate with and he always gives a straightforward answer when you ask him questions in office hours. Overall I would recommend him to anyone trying to take the course.
Jason Filippou CMSC250 Expecting a C+ Anonymous 05/04/2021	Say what you will about CMSC250 but I think Jason makes the course all the more enjoyable. The course is difficult (hence my grade, which is due in part to slacking off for the first exam) but Jason explains the material in multiple ways which is extremely helpful. Additionally, there are many resources that are available in the class that exist solely to make the life of students easier. He is a very sarcastic and frank individual, so if these characteristics in a professor don't bother you then Jason is a perfectly acceptable option for this course. Something I wish I had known earlier on was the GSS sessions and 1-on-1 tutor sessions available through the Iribe (ask your counselor). These became especially useful when office hours were full or you're someone who just needs more personalized help.
Jason Filippou CMSC250 Anonymous 04/30/2021	Jason's lectures are amazing. He is very thorough with his explanations and examples, and he makes an effort to make his lectures engaging. His slides are very detailed. There is a lot of HW, but it is manageable if you don't start it on the last day and all of it really helps with the exams. He is very caring about his students and adjusts the course to fit his students' needs.
Jason Filippou CMSC250 Expecting an A Anonymous 04/29/2021	Jason is a great CMSC 250 teacher. He explains the concepts well and his lecture slides are very descriptive towards the process and logic behind every topic. Jason is very open to feedback and wants his students to succeed even providing extra credit opportunities and video announcements relating to the course. On the topic of Jason he is very down to earth and tries to connect with the students. It's always a good time in his lectures and I look foward to meeting him in person once fall opens up!
Jason Filippou CMSC250 Expecting an A Anonymous 03/01/2021	Anyone who thought Jason was a lousy professor was simply caught lacking. His lectures are great and the topics are explained well and the HW and exams are not that hard if you've paid attention to the lectures and done the practice problems in the textbook. Yeah if a majority of the class does badly on an exam or HW he will say "wow you all got rekt" or something like that, but it's all in good fun and very clearly not meant to be hurtful. I think y'all are just mad because he made you realize your late-night cram sessions aren't a good way to study and you lost sleep for no reason. Don't slander his name because you got caught lacking.
Justin Wyss-Gallifent CMSC250 Expecting a B Anonymous 02/08/2021	Justin was a lifesaver during Zoom U. He was very knowledgeable and taught everything clearly. He was very good at engaging with his s tudents during lecture and they could ask questions. 100% the best professor in the CS/Math dept.
Jason Filippou CMSC250 Expecting a B Anonymous 01/11/2021	Good lecturer, and explained the topics well, which are important to know. However, online transition was rough. Hard hws and exams, and send emails that berated us. He also downcurved our grades when clearly the opposite should have happened. However, he was getting a lot of abuse from jerk students in the past who felt entitled to a good grade no matter what, so it's not completely his fault; he just cracked. Future semesters should be smoother.
Jason Filippou CMSC250 Expecting a P Anonymous 01/03/2021	His name is actually Jason, I don't know why he has a different name here. He is a very passionate and caring lecturer, one of the few that you will come across. He is a millenial, so he will talk to you like a big brother. I took him in Spring 2019 when we went into online classes and thought that he did a great job of teaching. A lot of people had problems with his communication style and complained about him to the department but he was definitely worth my tuition unlike Dr.Yoon. I wouldn't sweat about his long e-mails etc. Take him, he is a great lecturer. His communication channels and methods can be confusing sometimes so that would be feedback to Jason from me. Jason, please keep your communication short and perhaps use piazza since campuswire wasn't any better.
William Gasarch CMSC250 Expecting an A abhimod 01/03/2021	Class was challenging but very doable and I learned a lot. The grading was very fair and lenient in a lot of cases. Office hours were very easy to go to.
Justin Wyss-Gallifent CMSC250 Anonymous 12/29/2020	Even though it was his first time teaching this course, he was very knowledgable about the material and his lectures were very interesting and helped prepare us for exams.
Jason Filippou CMSC250 Expecting a B+ Anonymous 12/22/2020	I took this course in Spring 2020 Pros: + It is extremely obvious that he is passionate about class content. lecture is never boring. + At the end of the day, he does care about student long term understanding and success. + Pretty funny at times. + Transparent about how he grades questions, and what the curve will be. + Lecture content is extremely digestable. + Is quite adaptable to extenuating circumstances. Cons: - Has made unprofessional announcements which increased everyone's stress levels (if you took the class when I did, you know what I am referring to). If he has problems with individual students, then he should email them individually. - Partial credit is sporadic, sparse, and brutal. On proofs, you can lose 5-7 points immediately for not explicitly stating certain statements. Likewise, some probability problems will cause you to lose 10 points for calculation mistakes, even if your work is correct. In his defense, you may know about these ahead of time, but it's still frustrating to lose a significant amount of points for little things.
Justin Wyss-Gallifent CMSC250 Expecting an A- Anonymous 12/22/2020	Very hard class but his explanations made them doable. Exams were timed, but not on Zoom.
David Sekora CMSC250 Expecting an A Anonymous 09/16/2020	I'll offer a differing opinion, as these reviews seem to skew negative. Course work was difficult but manageable. As the course was asynchronous, homework was often used as a way of developing understanding & building intuition. Quizzes were straight-forward (just checking that you understood/paid attention to the lecture). Exams were difficult but David gave ample time for each (24 hours for the first, 48 for the second, 72 (I think) for the final). David wrote interesting problems and explained concepts well. He was a bit overly reliant on slides, which, in my opinion, aren't conducive to a productive learning environment. Having said that, most piazza posts were answered quickly or at least by the next morning. Occasionally, answers were curt/dismissive (fairly, in my opinion), but, mostly, answers were in-depth and helpful. Additionally, David gave a ton of partial credit and dropped enough quizzes and homeworks to potentially curve substantially. If you are not good at self-learning, you may struggle. Be warned, however, that self-learning will only be further emphasized as you continue through college. Given all of this, I think David is a fine teacher and will only become better as he gains more experience. He clearly wants his students to do well. It may be difficult, but don't confused difficulty with malevolence.
David Sekora CMSC250 Expecting an A Anonymous 07/11/2020	You would think Sekora may be understanding as he is relatively young. But the class was very unorganized. With his method of updating slides for classes, there is absolutely no way to being able to keep track of the order. David also makes quizzes and exams much harder than what he goes over in class, and doesn't even bother to touch on problems that my give students an idea of how to apply them to other situations. He explains concepts, and sends us off expecting you to be able to handle any situation. He is terrible at writing problems as well, where he writes them in a way they could be interpreted several ways, where he would like a very specific answer which usually doesn't relate to any problems he does. Overall, trash teacher and do not sign up.
Jason Filippou CMSC250 Expecting a B- Anonymous 06/25/2020	Great professor. Always prepared for class and puts in so much effort into them. Did have some crazy things happen this semester but Jason honestly tried his best and students needed to cut him a little slack as it's been challenging all around. One of the most detailed and organized professors, I never was confused about what was going on. Sometimes he does make mistakes during lectures but he'll correct it if someone points it out. It was a hard class in general though, unless you pretty much already know what's going on. Grading can also hit hard too with grading proofs and stuff, but there are regrade requests. Acceptable workload and all the assignments were helpful for the exams. Really enjoyed his class and I appreciate him and his class a lot.
Jason Filippou CMSC250 Expecting an A- Anonymous 06/09/2020	This professor sent an email to his entire class of 250+ people saying ‘all lives matter’, more than 2 weeks after the course ended. This is in the midst of the nationwide civil unrest following the death of george floyd in 2020.
Jason Filippou CMSC250 Expecting an A kjmehta 05/17/2020	Really really good lecturer. Class was properly tough. Kinda scary though

Jason Filippou CMSC250 Expecting an A- Anonymous 05/07/2020	Jason is a really nice professor. He is extremely approachable, he makes jokes in lectures, and his lectures are extremely thorough and easy to follow. He likes to break them up with a small check your understanding type question and does his best to walk around the classroom and answered questions. That being said this is not an easy course. This requires a lot of work and studying. His exams tend to be hard and such that if you mess up one question bad you look at a B. His grading is fair, and I never felt like I lost more points than I should have, but the class was challenging. It makes you think in a way most of us are unfamiliar with doing. If you go to office hours, he will do his absolute best to answer your questions, and I always left feeling better. GO TO DISCUSSIONS -- DISCUSSIONS ARE IMPORTANT they will go over practice problems exactly like the homework WHICH HELPS A LOT and they also will go over material Jason will not cover but expects you to know, or will reiterate material that was complex and confusing in lecture. The TAs are really helpful. The class is hard, but Jason is really nice. I highly recommend taking his class if you have to take this course.
Jason Filippou CMSC250 Expecting an A Anonymous 05/03/2020	Great guy who seems to truly care about his students. Interesting lectures
Jason Filippou CMSC250 Expecting an A Anonymous 04/27/2020	Jason is easily the best prof i've had here so far. PROS: - lectures are engaging and slides have extensive explanations (he goes at a good pace and occasionally stops to answer questions, has his TA's in the lecture so they can reach all the students w/ questions efficiently) - exams are very fair (95% is loose variations of problems from lecture/quizzes/HW, 5% is a challenge question) - jasons a solid guy -- pretty funny, caring, etc. (really wants to set up his students for success in 351 and other upper levels) - i personally like the math part of cs more than the programming & found the logic/proof aspect of the material in 250 very interesting, and jason presented it in a pretty clear way. CONS: - the grading with this class can be annoying occasionally, i remember losing 10-15 points on HW's for small mistakes here and there, but the TA's are solid with accepting regrade requests - his daily (or hourly lol) elms announcements can get annoying but thats really just because he doesn't want anyone to fall behind/forget about an assignment/exam
Donald Perlis CMSC250 Expecting an A+ Anonymous 04/10/2020	Lectures can be pretty boring/dry, but the content is gone over well both in lecture and discussion. There is more than enough practice for the exams from the discussion sections even though he does not provide practice exams. Exams are pretty straight-forwards.
Jason Filippou CMSC250 Expecting a C Anonymous 12/21/2019	Fair professor but can be really unapproachable/rude with the way he responds to students' piazza posts and elms messages. There are pop worksheets (basically quizzes to make people attend lectures) that are graded on "participation" but are actually graded on accuracy. Sometimes he is nice and tells us when to expect a worksheet. He goes over fairly easy examples in class but the homework and worksheets are usually much harder so if you didn't take good notes or rewatched his lecture, you'll be very unlucky for the worksheet. He also curved DOWN the entire semester since people were doing pretty decent in the class but since students didn't too hot on the final, there ended up being a slight curve up. Main pro: records lectures and has great TAs Main con: expects you to know the material completely once it's taught (hence the timed worksheets the following lecture) and expects you to know confusing notation that was barely taught
Donald Perlis CMSC250 Expecting an A Anonymous 12/18/2019	Prof. Perlis was a great choice for CMSC250! Take his section if you can. The good: Lecture notes and discussion practice are thorough and updated frequently on ELMS - textbook not even required! Exams were fair in both difficulty and length, with averages around the department norm of 80. Of the homeworks (~2 per week), one easy ("A") and one hard ("B") version are dropped, and one midterm as well, if it benefits your final grade. Feedback is prompt, and Prof. Perlis is always willing to help you understand topics! The bad: Lectures can sometimes be a bit dry or repetitive - staying attentive can be difficult. "B" homeworks are quite a bit more challenging than the exams, and often require you to think outside the box to get full points. My advice: GO TO CLASS. Ask TAs for help in discussion! Start your homeworks (especially "B") homeworks early. Also, ignore the older reviews for this class - Prof. Perlis no longer assigns quizzes in discussion.
Donald Perlis CMSC250 Anonymous 12/18/2019	This class made me enjoy mathematical reasoning. Perlis is not very strict on notation and is more concerned with the overall mathematical concepts, which is nice. I bought a textbook but never had to use it because his lecture notes are very detailed. His exams are almost entirely based off the homeworks, which makes studying for them easier. He's a nice guy too and gives a lot of info on what to expect on the exams.
Aditya Acharya CMSC250 Anonymous 12/12/2019	Class was fun. Very mathematical and rigorous. Actually prepared me pretty well for 351. He posts lecture notes, which I feel are more helpful than slides that other instructors use. Homeworks and exams are hard but he curves generously. If you're looking for an easy time though, avoid him.
Aditya Acharya CMSC250 Expecting an A Anonymous 12/12/2019	Knows his material. Loved that the homeworks were challenging and collaboration was allowed. Had to put a lot of effort but personally learnt a lot

Fawzi Emad CMSC250 Expecting an A Anonymous 11/27/2019	Fawzi is an amazing proffesor, one of the best in CMSC. He makes topics that could be really hard as easy as possible. Homework always fits well with the exams. Warning that he has a dry sense of humor so if you're not prepared for it you might think he's making fun of you. Hilarious and cares about his students.
Anthony Ostuni CMSC250 Expecting an A Anonymous 11/04/2019	Perfect!
Jason Filippou CMSC250 Expecting an A+ Anonymous 10/30/2019	Easily one of the worst instructors I have ever had. Makes silly mistakes nearly every lecture and uses nonstandard terminology that makes no sense to mathematicians. For a discrete math class, I feel like the topics could have been introduced more rigorously with precise definitions and more formal proofs. This guy once said that "the rationals are closed under multiplication" and that "the derivative of a sequence is undefined, so it is zero everywhere," or something along those lines. Instances like these made me question if this guy was even qualified to teach a discrete math class. In fact, they should change the name to "introductory proof writing for computer scientists," or just allow the math department to teach the topics instead (in fact math310 covers more content in greater detail so it is a mystery why it does not exempt students from cmsc250). The quizzes that he has started doing in Fall 2019 are basically joke questions whose only purpose is to force students to attend his lectures. Also, the guy is super passive-aggressive and sends out ELMS announcements pretty much every day. One of the head TAs is extremely cringy, and although I would say he's overqualified for the role, he's super unprofessional and tries way too hard to be likable. Also, homework problems prepared by this TA in question often use ambiguous terminology such as "simple" or "new" that is never given a precise definition in class.
Aditya Acharya CMSC250 Anonymous 07/14/2019	Taking him for CMSC250 in Summer 2019. He is a good instructor at what he teaches but I will never understand why he insists on making the homework feel like hell. I hate having to rely on going to office hours to understand it. It never makes me feel prepared for any kind of midterm; if anything, it only makes you feel worse. Additionally, he doesn't put in grades into ELMS, which makes it harder to calculate your own grade in the class (something that I don't understand either). This makes always ask questions about what the curve is going to be, and we don't have a generally good feeling about how we will do.
Clyde Kruskal CMSC250 Expecting an A Anonymous 05/29/2019	Kruskal made it clear he was not too excited to be teaching 250 this semester. He is a knowledgeable professor but during lecture he would often refuse to answer questions and would sometimes make students feel unintelligent. He was not very responsive to students' concerns and the class was not very well run. If you take him make sure you attend lecture because he purposely does not record lectures and there are often no slides posted (and if they are, all the examples are absent and say "do in class").
David Sekora CMSC250 Expecting an A Anonymous 05/29/2019	The class was very disorganized. There was a lack of slides and it was clear that TAs and professors did not communicate (TAs often did not know what we were learning in lecture), nor did the professors seem to communicate with each other. Some of the homework problems were ridiculously hard but for the most part TAs were fair in grading both homeworks and exams. The midterms were pretty fair and similar to the homeworks except for the occasional challenge question, but the final was much longer and harder than the midterms despite having the same amount of time to finish as the midterms, making it an unfair exam (average was less than 60%). It took a long time to get grades in and the class did not have much structure to it, although I know that this was Sekora's first time teaching 250. Sekora was an engaging lecturer despite my complaints with the way the class was run.
David Sekora CMSC250 Expecting an A Anonymous 05/11/2019	Terrible terrible teacher. Posts slides online but it is completely useless, any problems in the slides are marked "do in class". Teaches on the fly without clear formatting whatsoever. Waste of our time.
Junchi Chu CMSC250 Expecting an A Anonymous 05/02/2019	Honestly he's a great TA that clearly cares a lot about his students and their success. He made a review sheet for our exam when the prof didn't provide one, and attending discussion with him definitely boosted my final grade. Very understanding with any issues / conflicts students had.
Jason Filippou CMSC250 Expecting an A- zainbhaila 04/06/2019	Good lecturer. Exams were fair, but you need to study and stay on top of things.
Jason Filippou CMSC250 Expecting a B Anonymous 01/30/2019	Jason was a decent teacher and I liked his style of handwriting problems step by step during lecture. However, sometimes he could be unclear about the small details, such as how to write an inductive hypothesis for strong vs weak induction, and the TAs would have to clear that up during discussion. He also could get very defensive or annoyed if people asked a lot of questions during lecture, which was entertaining once in a while. The homework problems could be hard but go to office hours early in the week and some of the TAs were very helpful (I figured out early in the semester that some of the TAs were very confusing and explained things in a super complicated high-level way while other TAs explained the problems clearly so be careful which office hours you go to). A lot of the times Jason would make mistakes on the homework questions and then have to send out an announcement, that happened quite frequently throughout the semester so pay attention to your ELMS announcements. At the end of the semester Jason dropped our lowest homework grade which was a pleasant surprise because it wasn't in the syllabus and he didn't tell us until then he was going to do it. The two midterms were quite fair and very similar to the homeworks, so the best way to study was to go over the homework problems and then if you have more time go over class and discussion problems. I thought the final was much more difficult because a bulk of it was on a topic (countability) that we had learned at the very end of the semester and had only learned very briefly. I did the worst on the final but ended up getting a B in the class because Jason curved a decent amount (6-7%) considering I didn't think he would curve at all. In general for this class I would say keep on top of your studying and every week go over the problems from lecture and discussion. Ask a lot of questions in discussion and office hours (but be careful who you ask your questions to if you want a clear concise answer lol).
Jason Filippou CMSC250 Expecting an A- Anonymous 12/13/2018	Jason is disorganized and disrespectful. I would not recommend taking him. Also, don't even bother to go to class. He records all his lectures and even so you won't learn anything from them that you couldn't learn from reading the slides.
Clyde Kruskal CMSC250 Expecting an A+ Anonymous 12/13/2018	Clyde's class is difficult. His homeworks are the same as Eastman's, but different from Jason's. I found that the "prep" and the self-study sheets that Jason would post around midterms or throughout the semester were very helpful if you did all the problems listed. Most of the exam problems look just like the ones on the practice midterms but expect a few curveballs. As an instructor, Clyde is objectively frustrating to follow. He'll take examples from the slides and change them so that if you don't pay close attention the whole time, you may end up lost. Asking questions in class is good. He won't demoralize you if you have the balls to ask a question, but if you try and answer a question that HE asks, and you get it even slightly wrong, he will not be forgiving. Just before Thanksgiving, he taught a lecture that was like an intro to algorithms, and there were only 15 of us in class that day (weather was bad and it was the day before break). I guessed the answer to one of his problems, and upon learning that I got it wrong, he followed it up with "I guess you really don't know anything." It's objectively a terrible teaching tactic, but the TA's will be a lot more helpful in giving constructive feedback during discussions or office hours. My tips for surviving the Clyde: 1. I definitely wouldn't have survived without this. Go to discussion. The TA's will go over problems more in-depth than he does and will answer your questions without ridicule. I personally never went to office hours but if that's your thing hey more power to you. 2. Do problems from the textbook to prepare for exams. I got a 78 on the first midterm when I didn't do this, and then a 98 on the second when I cracked open the book. 3. Look back at the homework to get an idea of the types of questions that can come up on exams. Oftentimes, midterm problems will be carbon copies of these with a few words or numbers changed. 4. Follow along during lecture on a laptop with the lecture slides. I found it helpful to get some notes a minute or two in advance of him covering it. Side note - Jason makes the slides and Clyde lectures on it, so that's why it seems like he's only reading it for the first time. Also, Clyde will sometimes skip over a lot of slides at once because he feels it's not important, but it can be helpful to get a couple more examples under your belt while he's rambling. 5. Try to keep your cool. Clyde is so frustrating, I can't stress this enough, but if you're taking his class, the best you can do is get your bearings and learn more in-depth on your own time (which honestly can be during lecture). I hated his class, but I'm taking 351 next semester with him because I'm a freshman and register last so wish me luck.
Donald Perlis CMSC250 Expecting a B- Anonymous 12/11/2018	I couldn't really understand what he was saying in lectures because he goes on so many tangents. I attended Jason Filippou's lectures instead, and quickly understood concepts better. Barely scraped by with a B-, though because 250 was tough for me as I was new to that style of math. Tough class, but interesting and insightful. I learned a lot, but I would recommend taking Filippou instead if given the chance.
Jason Filippou CMSC250 Expecting an A Anonymous 09/23/2018	I took 250 Fall 2017, my 1st semester of freshman year (no joke here). I thought he was a great teacher. The homework I recall could be difficult at times, but if you did them then you'd be ok. Even though my TA was terrriiibble, I still got an A. So I guess a mix of Jason + working hard. I'm taking 420 now and I have Jason again. It is lit
Clyde Kruskal CMSC250 Anonymous 05/03/2018	If you can take Jason Filippou instead for CMSC250, you should. Kruskal knows the material and can teach it, but he always complains about his lack of interest in CMSC250 and even when he teaches, skips over steps. He thinks that everyone knows about certain things, so he'll just skip over things, but most people attending the lecture may not know what he is doing. However, he does like to joke around and have some fun, so his lectures can be interesting on occasion. Normally, I attend his lectures and then look at Jason's slides on ELMS, which are more in-depth and have better examples. If you have to take Kruskal due to the fit of your schedule, you will be fine, but I hope that he has regained excitement in teaching CMSC250.
Rohan Chandra CMSC250 Anonymous 04/23/2018	One of the best TA's I've ever had. Rohan goes out of his way to help the students and I actually learned more from him than from the prof. He sends out useful practice resources before exams. Other than being very knowledgeable about the subject, he actually cared if we learned the material. I couldn't have succeeded in the class without him
Roger Eastman CMSC250 Expecting a B+ Anonymous 04/11/2018	Nice guy. Gets a little frazzled during class and always read off the slides. Helpful in office hours but overall very average, not the worst
Jason Filippou CMSC250 Expecting an A- Anonymous 03/15/2018	Had him for 250 in Fall 2017 and he was great. Jason's homeworks can definitely be long, but they're straightforward if you pay attention in class or know how to search for information you don't know. Exams were also very fair. His exams always had a free bonus point question on topics unrelated to class as well. Overall, I would definitely recommend Jason for 250
Jason Filippou CMSC250 Expecting a D Anonymous 12/30/2017	I had the misfortune of taking Jason for CMSC250 in the Fall 16 semester. It was not a pleasant experience. We had quizzes in discussion every wednesday and it was on material we would review then and there and be tested on it immediately after. Not how I learn. His lecture slides were too...brogrammer like. He made "post lecture" quizzes every time after lecture due online 10 minutes before our next lecture. These were pretty stupid and I never did well on any of them. The homeworks were really hard and I could never do them on my own. I found myself in the TA room doing them every week which was really frustrating. As a lecturer he is very dull. Very technical and doesnt explain things very clearly. I had to rely on TA's a lot just to understand the whole point behind proofs and induction. And when it came time for combinatorics, I was eaten alive.... Jason is pretty immature. At the end of my semester, not only did he NOT CURVE but he sent out a message on ELMS where he defended himself for his lousy teaching and blaming it on what he called a "un sexy bowel decease". I understand he has become the only option for 250 and he apparently sounds better for 420, but if you have to take him for the former, I suggest you spend a lot of time studying with a group or become buddies with a TA. If you have other options, avoid Jason.

Fawzi Emad CMSC250 Expecting a B Anonymous 05/19/2015	Best professor in the Computer Science Department, and I don't think it can even be debated. I've taken him with both 131 and 250. Fawzi teaches every course with a genuine interest and enthusiasm that just makes you want to learn and grasp every concept. His ability to teach with clarity is absolutely amazing. In addition, he's always there to help if you have any difficulties with the material. His quizzes, homeworks, and exams are incredibly fair and with a good amount of studying, doing well in the class shouldn't be an issue. CMSC250 is traditionally known as one of the weedout courses, but with Fawzi it never seemed like one. If you ever get a chance to decide between Fawzi and another professor, you pick Fawzi, end of discussion.
Fawzi Emad CMSC250 Expecting an A Anonymous 05/15/2015	Fawzi is the best teacher I have had at UMD, if not the best teacher I've ever had. He knows the material very well, is actively interested in it, and loves to spark interest in others. His tests are not necessarily easy, but they are a very fair reflection of the course. The best part about Fawzi, though, is that he's just a really cool guy. He has a great balance of nerdy, intellectual habits and a perfectly normal personality. He's the type of person you'd want to have as an uncle.
Fawzi Emad CMSC250 Expecting an A lordwill753 05/06/2015	Fawzi was a really fun and engaging professor for 250. Although the material in the class is fairly difficult, he manages to make the material fun and engaging sometimes. He's actually funny, which is another plus since his jokes will probably wake up the class if they ever decided to doze off. Tests were pretty fair too, sticking to questions that were on quizzes. The homework assignments were challenging, but at the same time doable. Overall a great class for me, and I definitely would take Fawzi again if I could.
Evan Golub CMSC250 Expecting a C wonderful_wonton 05/18/2014	His lectures are good but he's very self-absorbed, biased and will passive aggressively undermine students he doesn't like. He wastes lecture time on repeatedly describing his past exploits catching proofing errors in other people's work, but then leaves core topics for TAs to teach in discussion. Too few exercises & worked problems overall. Pedantic, with heavy focus on empty formalism. He starves his course without adequate worked problems, especially since he places so much emphasis on extremely formal procedural steps. You often can't tell if you got points off because of some formal expression nicety you didn't follow or because your whole proof was wrong. It's difficult to learn well when you have only a couple of examples for each core topic to work off. If he didn't leave so much core teaching to his TAs, the discussion sections could be used for more exemplars and working of problems, but as it is there is inadequate work. He compensates for this all by having limited coverage of topics and never gets to graphs at all. All he really cares about (obsesses over) is formulaic formalism, it seems. Yet, he hands out a lot of A's simply because students who want to memorize off the few worked examples you get and the limited coverage his course provides can do well in his classes. The people who have it worst are those who want to do their own work (not get solutions from other people) and not memorize problem-solving. The average students who do well in his class are ones who band together and pool their resources to create a set of solved problems. What they are doing in effect is compensating for how he starves his course for worked problems and exercises. His personal biases and prejudices against individual students comes across strongly at times in the classroom, like when he snaps impatiently at a student he clearly thinks is a fool. Personality and appearance-wise, he's rather like that character in the Simpsons who runs the comic book store.
Jandelyn Plane CMSC250 Anonymous 02/19/2013	I know this is late but I had her for 250 over the summer. I was a little scared because I've heard crazy mixed reviews, but there is nothing to be afraid of. She is very kind and helpful but most importantly she wants her students to succeed. She knows that the material can be confusing so she goes over it and makes sure the class understands before moving onto the next unit. What I really love about her is how approachable she is. She had set office hours but I sometimes showed up at her office randomly and she still was happy to help. She is really helpful about exam grading too. She will explain to you why you got the grade you did and will negotiate with you if you don't think you deserved it. There was one time I misread a question and would have lost a lot of points but I explained that to her and she let me rewrite my answer. She is overall a very understanding and caring professor. She made 250 a fun class (like we were doing puzzles rather than long boring proofs). I recommend her not only as a professor but also an adviser (you can ask her about anything!)
Clyde Kruskal CMSC250 Expecting an A zaqu413 12/22/2012	Lecture: Kruskal seemed to be a little out of his element this semester (Spring 2012). He supposedly never uses power point, but was forced to because Meesh said her class and his class had to keep up with each other. I didn't really learn much from the power point slides, most of the interesting tricks came when Kruskal would steer away and do one of his 'fun' problems. He was disorganized and late to every class. I honestly don't know how I learned during lecture, but I did. So I would suggest going to lecture (no pop quizzes or anything like that though). Homework: Assigned weekly, and very hard. I took MATH310 and MATH406 (A+ in both) already, and I thought this homework was very difficult. Quizzes: On Monday's during discussion. Usually pretty easy, just look over the slides. Exams: the midterms were long, I kind of finished them, but I didn't really get to check my answers. Final: He randomly gave us 2 hours and 7 minutes to finish the final. When I asked him why he just said "I have my reasons" which is the response he gives to just about everything... The exam itself was not that bad, I got a 90% but the class average was a 60%. It was only a little bit longer than the midterms, but it was harder. **Finally I would like to say that I considered testing out of this class, since I was a math major I could have probably passed the placement exam. But I wanted the free 4 credit A. Turns out this class is not a free 4 credit A no matter how much math you know. Kruskal makes the homeworks too hard for that. That being said I think that you should take this class rather than test out of it, I learned a lot of stuff (especially Induction stuff, which isn't covered very well by the math dept. but Kruskal did a extensive covering of induction). ---------------------------------------- ---------------------------------------- ---------------------------------------- ---------------------------------------- I also had Kruskal for 351: He did a much better job in 351 than he did in 250. I think he just wasn't really into the 250 stuff. In 351 his exams and HW were very hard, but he curves like crazy so don't worry about it (like a 60% = B for our class). This seems weird, but it is done because it is hard to test algorithms. The only thing I didn't like was that there was one midterm that was 40% of my grade, the final was 50% and homeworks were 1% each. On exams if you are asked to make-up an algorithm on the spot just make one that works and disregard efficiency, you get a lot of points for one that works. Efficiency will get you more points, but just move onto the next question and try for efficiency if you have more time at the end of the exam.
John Aloimonos CMSC250 Expecting an A Anonymous 09/23/2012	He admittedly does not cover the material he is supposed to, and whenever he does, it is always a very cursory overview whereas Fawdi Emad's section comprehensively went over all of the material, yet we were all given the same exams and quizzes, all written by Fawzi. Seems pretty unfair, eh? On the bright end, Yiannis is a very nice person who appreciates other people's input. He may not be the best professor, but thankfully this class is extremely easy to begin with and you can be fine by just teaching yourself everything from the textbook.
Clyde Kruskal CMSC250 Expecting a B Anonymous 05/01/2012	You have to work your butt off in this class because it is a hard class to begin with. But, to top it off, the professor doesn't teach well. Hopefully you have a good TA
Donald Perlis CMSC250 Expecting an A Anonymous 02/20/2012	Honestly, going to class is optional and so is reading the book. However, I hear the book is excellent in clearing up most of the topics covered. Also, find someone that has taken the class before because at some point they find out the textbook is available online... His exams are based on the homeworks and almost identical to the practice exams he puts online. I can't comment much on his teaching style because I never paid attention in class. But he posts notes up online if you need, I never used them. I never studied for this class. Understand the homeworks and you'll do well. I loved Perlis because the way he grades helps out everyone and does it in such a way that is beneficial for everyone. He has no need to curve but he might. I definitely recommend him. I will say that some of his classes are extremely boring and I learned nothing from them.
Michelle Hugue CMSC250 Expecting a B+ Anonymous 01/26/2012	This class was one of the more boring/frustrating ones that I have taken here at UMD. It seemed like the curriculum we covered was just all over the place, and I didnt feel like I learned much at all from this class. The graduate teaching assistants for this class were not good at all; they didnt care very much about the students and were horrible at grading exams. A lot of people found 5-10 points worth of mistakes on each of the exams, in addition to the fact that many of the points awarded were subject to the grader's own opinion, rather than actually getting a right/wrong answer. As for Dr. Hugue, most of the stuff mentioned below is true. She is pretty crazy, which can make the class funny at times but will also annoy you to no end if you actually are confused about something and want to learn the material. In lecture it seemed as though she just went over random topics with no real sense of organization or purpose. I had to teach myself everything for the assignments and exams. She is a really nice person who will listen to you after class and respond promptly to email. If I had to choose over again Id take this class with Perlis, because I learned more from him the one time I was in his lecture than I did all year in Dr. Hugue's lecture.
Michelle Hugue CMSC250 bigbabby 12/20/2011	Hugue...oh boy. I thought the subject matter of 250 was pretty boring to begin with, and Hugue didn't change my mind. Lectures start off with a TA teaching for the first few minutes, then Hugue going over slides mixed in with random stories about her life. Homework is easy, about 20 minutes a week, and quizzes are just as easy, as long as you've done the homework and stayed semi-conscious in lecture. Tests are okay, alot of partial credit, which is great if you mess up on a proof. Hugue isn't great but compared to the other professors I'd prefer her. From what I hear the other 250 professors are like Hugue minus the stories in lecture, and that's the only thing keeping me from falling into comas during lecture. Also, she's much nicer than the other professors. She wants the class to do well and promises to curve/give partial credit/etc. if it will help the class.
Fawzi Emad CMSC250 Expecting an A+ rockinbassman 03/21/2011	Fawzi was a great teacher. Fawzi sets his expectations at a reasonable level and then expects you to meet them, unlike many teachers that expect WAY too much and then curve. Curves always seem to add more stress to the class than necessary. Fawzi always did a good job conveying his thoughts, and was also good at coming up with multiple ways to explain the same concept for people who were struggling. Fair exams too. Don't expect much of a curve, but you shouldn't need it since he's fair.
Donald Perlis CMSC250 Expecting an A Anonymous 02/15/2011	Easy class. Weekly quizzes and homeworks given, but mostly re-iterate simple topics. Grading in the class is set up to help immensely. Honestly, the material is not too difficult, so there isn't really much to say. Perlis' lectures are okay, but attending them is not actually necessary to understand the topics.
Donald Perlis CMSC250 Expecting an A Kristian Sooklal 12/23/2010	Perlis is a great professor to take CMSC250 with. Coming into this semester, I read ourumd.com's reviews and I was pessimistic about this course because of the low reviews and comparatively low GPA that Perlis had, but after taking this class I can assure you that Perlis is fair, if not even easy to take. His tests are fairly easy with a major recurring focus on induction, and his homeworks are pretty fair as long as you pay attention to details. The quizzes are extremely easy and are just attendance points. The curve is significant and he dropped the lowest 2 homeworks and 2 quizzes. Combined with the curve, this allows you to pretty much have an 85% and get an A. I'd definitely take 351 or whatever other classes he teaches in the future, because I enjoyed this class, learning about new mathematical concepts, and getting the A at the end.
John Aloimonos CMSC250 Expecting an A+ xenonscreams 05/20/2010	He is the most accommodating person I've ever met. If you have a problem and you address it to him, he will absolutely help you out. He is completely engrossed in the success of his students. This is an extremely rare quality in a professor. There are only a few things holding me back from giving him five stars. Firstly, he goes on a lot of tangents. If you are the type of student who learns solely from lectures, it might be difficult since sometimes he does not cover all of the material. Secondly, he seems to have difficulty teaching the students who have difficulty grasping the concepts. If you really have trouble with theoretical math and logic, it might be best to take it with a different professor.
Donald Perlis CMSC250 Expecting an A Anonymous 12/28/2009	Perlis is a pretty good professor. He is extremely fair on every assignment, quiz, and exam in terms of what he asks and how he has the TA's grade it. He tries very hard to make the material interesting with his own little twists in how he presents the topics. However, the topics were fairly easy in general, especially if you come from a strong math background, so class can seem like a waste of time. Also, he mostly just presents stuff from the book, so you technically don't really need to go to class at all if you can just learn it from the book. Though this class, while being easy, will introduce you to some very interesting areas of math which I'm assuming will be covered in more detail in later classes. Overall, you've got a few very interesting topics, a pretty good professor who is at least very fair in grading, and not much hw (just one short assignment due each week), making this a decent class to take.
Donald Perlis CMSC250 Expecting an A Anonymous 12/24/2009	Coming from MATH, I can say 250 is an unique course. It takes elements from different math categories that you have either seen (As a math major) or will see (as a CS major). Some overlaps include elementary number theory (seen it if you took MATH406), counting (seen it if you took STAT400), and logical equivalences (CE majors probably have already seen truth tables and logical curcuits. Although, I was very familiar this class is not a walk in the park. Hence the overall GPA of the course. If you want to get a 4-credit A or B, take this class with no one other than Perlis. He has two methods: Method one: 15% quizzes, 15% homework, 20% midterm 1, 20% midterm 2, 30% final Method two: 15% quizzes, 15% homework, 30% best of two midterms, 40% final Your grade is determined based on the highest of the two methods and the curve. This class with Perlis is really convenient, especially if you are taking 212 or 313. I suggest taking this with Perlis if you are taking them, or take 250 and 212 or 313 separately.
Donald Perlis CMSC250 Expecting a B Anonymous 05/26/2009	This professor consistently confuses himself to the point where he wants to bang his own head on the wall and waste 25 minutes of our 80 minutes lecture time. His examples in class are completely irrelevant to the stuff on the quizzes and the final. The homeworks are challenging but if you memorize the examples solved in the book you will do fine. Final verdict: Because Perlis is incompetent at understanding the material himself, he is not the best professor to take this course with. It's like paying good tuition for someone who doesn't even know what he's talking about. Pick another professor.
John Aloimonos CMSC250 Expecting an A Anonymous 05/06/2009	Dr. Aloimonos is a great guy, good teacher, and interesting to listen to in lecture. Like some of the other reviews said, he covers the material really quickly and perhaps not in as much detail as they should be, but if you do the worksheets in discussion and/or study, you'll be fine. His lectures are good to go to because he covers a lot of stuff that other professors don't, and talks about philosophy and stuff sometimes (its always somewhat relevant though). He knows a lot, but if you don't want to study and don't already know some of the material, then maybe someone else would be better.
John Aloimonos CMSC250 Expecting an A Anonymous 03/20/2009	He is a great professor and a teacher. I mean he may not cover the subject material in any detail (u HAVE to read book to get stuff and practice for this class). But it is a fun class with him coz' he brings in so many higher level fun topics into the discussion. he is very knowledgeable and funny. recommended if u like logic math.
Donald Perlis CMSC250 Expecting an A Anonymous 01/12/2009	Perlis is an interesting guy, very frail. His lectures aren't difficult to follow, and his tests are ridiculously easy. I went to about 50% of lectures up until the first exam and got a 100 on it. I then did not attend one lecture for the rest of the semester, and still got a B+ on the final (left a lot blank, and did not review or study at all) and an A in the course. Sometimes he seems to get a little confused in class, but always answers any questions via email (which gets really annoying after a while, since he replies to the whole class). My recommendation is to attend all of the discussion sections, as this is where you will see what you really need to know.
Donald Perlis CMSC250 Expecting an A Anonymous 12/24/2008	Personally, I agree with some of the earlier complaints about Perlis confusing himself on some of his examples and problems, but he always corrects himself when he figures it out, by email if he can't in person. He also sends answers to any homework questions students ask him to the entire class listserv, which can be very helpful in figuring out the problems. The homeworks are hard, but considering that you have a week to do them and can ask questions about the assignments to the TAs (I personally had Peter Fontana, who I have to say made everything SO much easier) or Perlis in class or via email, they're not so bad. Quizzes are also hard, sometimes extremely so, but to compensate, he drops two of them at the end of the semester. He also drops two homeworks. As for exams, as long as you have a reasonable understanding of the material, they're quite easy. None of them are terribly long; a few large questions, a few short answers, a couple fill-in-the-blanks, and you're done. To make things even better, if you screw up terribly on one of the midterms, it gets dropped (though the other midterm and the final are made to count for more to compensate). All told, I found Perlis to be a very fair and nice teacher, which is a lot more than I can say for some others.
Donald Perlis CMSC250 Expecting a C Anonymous 12/23/2008	Dr. Perlis would post huge reviews online that were normally problems taken right out of the book and then changed a tiny bit... with a couple tricks. The range of grades in the class is very large. As any math major that is in the class will maintain an easy A, while pure CS students will struggle. The curve for our class was as follows: For each student grades were calculated as follows: Method 1: HWK 15%; QUIZZES 15%; TWO MIDTERMS 20% each; FINAL 30% Method 2: HWK 15%; QUIZZES 15%; MIDTERM (best of two) 30%; FINAL 40% The curve is as follows: A >= 85.6 B >= 76.0 C >= 58.5 D >= 47.7
Donald Perlis CMSC250 Expecting a c Anonymous 12/21/2008	this guy is the worst lecturer ever. he is all over the place, and has terrible handwriting. he insists on using markers that are half out on the dry erase board. you can tell that he knows what he is doing somewhere in his crazy little head, but he just cannot translate it into something other people will understand. the course itself is also rather dumb. most of it is spent formally proving intuitive things. ex. on the final, he gave a hint that 1+1=2.... okay this is all good and fun, but when it is graded off because you stopped your proof when things got that intuitive, someone needs to get shot.
Donald Perlis CMSC250 Anonymous 12/18/2008	THE worst professor ive ever had. unorganized during class, VERY sloppy notes, quizzes are often not relevant to anything gone over in class. his explanations are terrible because he gets confused with his own problems a lot. halfway through a problem he will realize he made a mistake and go back through the entire problem. homeworks are mostly hard. in my opinion he might know what hes doing, hes just terrible at explaining it. also, he'll spend an entire lecture on the same topic doing the same 2 or 3 problems. a lot of the class is based on learning things from the book or online. BUT, there is a HUGE curve!!! A >= 85.6 B >= 76.0 C >= 58.5 D >= 47.7 it saved me from taking the class again!!!
Donald Perlis CMSC250 Anonymous 10/16/2008	terrible, terrible professor!! is very unorganized, gives examples that make no sense, quizzes cover stuff not covered in lecture
Larry Herman CMSC250 Anonymous 08/06/2008	I second that the guy is anal. You should avoid him as much as possible ...trust me , start planning your schedule from avoiding any of his classes ... You will regret the day you decided "Oh, well, this class fit into my schedule"
Larry Herman CMSC250 Expecting a B pluralfacade 05/17/2008	He was pretty good at teaching the material. However, appraoching him outside of class is out of the question. He just does not seem to want to help people, and even gets angry when you send him emails asking about the homework. Tests and quizzes were pretty fair though.
Clyde Kruskal CMSC250 Expecting an A Anonymous 04/22/2008	Heh, what can I say about Kruskal... first off, I had him for both CMSC250 and CMSC351. He seems very averse to doing work, and though he is very smart he rarely imparts this knowledge on students in a way that really impresses people. His lectures can be disjointed (he never has slides) and it can be hard to follow what he is doing, most of the class was not able to learn the material from the lectures. On the other hand, if he likes the material, I feel like he is able to teach something. And he seems to be really passionate about algorithms. So there is a silver lining - if you understand and follow what he does, you can learn.
Donald Perlis CMSC250 Expecting a B Anonymous 02/28/2008	I've never seen a professor baffled by his own sample problem until I took this class. Literally, he would give us a practice problem over the listserv and then be unable to solve it the next day. He was disorganized and invariably gave an inaccurate description of his exam material. For example, his "cumulative final" had a small section at the beginning pertaining to early course work and the remainder of the exam was based solely in the material of the last two lectures. The average on that exam was... distressing.
Larry Herman CMSC250 Anonymous 02/13/2008	Herman is not a bad teacher; you will likely understand some material from lectures and take some solid knowledge away from the class. His tests were also quite fair in this class. He is, however, completely unapproachable before class, many times shrugs people off during office hours. He wouldn't even let me ask him if I could come to an earlier lecture session, because he was "too busy." He is also VERY partial to girls, often fawning and flirting.
