Super easy class if you've coded before (even just in Java). Never directly interacted with Justin because the course was pretty much self-taught, but I do recommend taking the course for an easy A and MATLAB experience.

This class is very easy, and as long as you do the work you should get an A/A+. Most people tend to forget the assignments because they're asynchronous, so don't forget to do them. The only thing I dislike about this class is MATLAB grader as it's hard to debug compared to MATLAB because the errors that MATLAB grader show cannot be easily traced, so I recommend writing code on MATLAB and then just copy-pasting it into MATLAB grader. In my opinion, learning MATLAB code and finishing the assignments can be a little bit annoying, but the TAs and Prof. Justin are very accessible, so make sure to reach out to them if needed.

Really great lectures, he's very caring and truly worries about his students and if you come up to him with questions he will be very nice when explaining and explains topics in a very straightforward and easy to understand way. However as great as he is, I had a very stressful time in 351 because of the grading issues that came with basically every assignment. TA's most of the time if you had something not resembling the rubric in a homework assignment, or just because based on their own judgement, will not take their time to read your answer and will not hesitate to slash off as many points as you can as possible (Many times I have gotten back as much as 20%-25% of my assignment just because the TA did not read my answer entirely, and I've had to explain very thoroughly in my regrades). I know this is not his fault, but he was very aware of the grading issue because we would get multiple announcements about how there would be over 100s of regrade requests for each assignment and exams. This would not be an issue if the grading was more careful in seeing if the student truly understands the topic instead of how close it is to the rubric, or even something as small if simplifying 1 more step would give the same answer. Oh and what the other reviewer below said is absolutely correct, sometimes I would compare homework answers after grades came out on grade scope, and classmates who wrote the exact same I did would get full credit while I would get -50% off or even the entire question wrong. Same thing if they had the same reasoning for more deep thought questions. Mind you sometimes you would have to regrade this multiple times to get your points back if the TA's were unwilling to check, and it wasn't for sure that you would get your points back. Lastly the reason that also made me give him a not so great review even though I enjoyed having him a lot as my instructor, the above issue of getting massive hundreds of regrades because of extremely inconsistent grading, got so bad that during the last weeks of school after the final they said that since regrade request numbers are always hundreds, they would not allow regrade requests for hw12,hw13 and the final exam. Our homework is worth 28% of our grade and people were relying on this to bring up their averages if they didn't drop them, and they even admitted they graded the hw "leniently" and the rubric would even say "anything reasonable even if not correct". My questions were not read, marked off points without explaining any reason because of the shortness of time with regrades from past assignments, and the final exam also had some grading inconsistencies. My final point, Justin throughout the semester said that the cut-offs would be lowered slightly below the regular cut offs to account for the grading inconsistencies, the ambiguous writing of questions on exams and etc. This was only 1% or so when confirming when my friends, which if I will be honest, 1% of the entire class is not enough to account to how extremely bad and up to the TA grading your assignments judgement is. And even if Justin offered to contact him regarding grading on hw12,hw13 and the final exam, he would only do this if you were borderline. Which, is kind of extremely hard to figure out when we did not have cutoffs published.

Lectures were great of course. It's Justin. However, the course could've been managed better, and rubrics for homework's and exam solutions could have been much less ambiguous, as well as the questions on the exam. There can be a time where you work with your friend on a homework, then you receive a 0/15 on a homework problem while your friend receives a 15/15 because the rubric is not as definitive and TA's judge based off their intuition and subjectivity. Same goes for exam problems, besides the fact that you obviously do the exam independently, you can have a solution that follows the gradescope rubric to earn a specific amount of points, but the TA can be subjective and not go off of what the rubric says and even give you a 0 for the problem for what should have been partial credit atleast. This may be a TA problem sure, but Justin leads the TAs and instructs them on what to do, so I feel there's a bit on him too as he could make the rubrics for homework problems and exams more definitive so TAs can't be as subjective. Exam problems were ambiguous as well to an extent, mainly the true/false portion, but some written responses as well, but the true/false was only a few points (typically 10 points an exam). Essentially, there could be multiple interpretations of a question which could make you believe either true or false based on the interpretation you go with. Overall, great professor along with his lectures of course. No doubt about that. He needs to be more straight forward about a few things though. The course wasn't difficult to manage so he did amazing with that, but there would be confusion on the ambiguity from the student and TA side, in terms of grading and interpreting problems.

Coming off of 250 with Justin, I was expecting to get torn to shreds with 351, especially with the stigma around the class. Given that I don't think Justin is the best at organizing courses, I think he and Erika had a great duo with her taking most of the nitty-gritty details like Piazza answering and course announcements. The class ran extremely well (definitely some improvements needed on the TAs and their grading in this course, but that's not on Justin) and I can still vouch for Justin's lecturing. Guy is one of the best at UMD, he could explain Dijkstra's to a 5-year-old. Tests and homework were extremely fair, an issue I found sometimes with the 250 homework, and both Erika and Justin made the course extremely enjoyable. I also had him for 241 this semester. Relatively smaller course, pumped out grading and got the concepts where they needed to be. Could definitely tell he was in his comfort zone with this course as his lectures were spot on every time. Tests were extremely fair and grading was good. Overall, 10/10 professor.

as we all know Justin is a great professor and that was the case with cryptography. definitely learned a lot and he didn't make it harder or easier than it needed to be, which is amazing considering it's his first time teaching the course. as a teacher, there is nothing that I can complain about. there is a fair amount of work but I think it's reasonable for a 400 level course. I'm giving him 4 stars because I felt there were instances where he was rather curt/rude when responding on Piazza. maybe that wasn't his intention because he's always very kind in class, but that is how it came across on Piazza. also no recorded lectures which was kind of annoying (i think he just really hates anything to do with online school) but at least he posts his notes from class online. overall, great in terms of teaching so I would recommend

The best teacher ever!!! Form your entire schedule around taking his class--it's worth it! About the class: - Weekly groupworks on Tuesdays: these are worksheets based on material from the previous few lectures and you work in groups to complete them - Weekly quizzes on Thursdays: these are based on the worksheets from earlier in the week and are fairly straight forward - MATLAB assignments: there are 4 assignments on MATLAB grader which are very easy to complete if you read the instructions - Homework (optional): the textbook problems from every section are a good way to reinforce the material taught in class (do them if you have time) About Justin: - He is a very funny and caring, which makes his lectures very entertaining and informational. He gives the best examples to reinforce the topics he taught and structures all his lessons in a way which is very easy to follow. Even some of the more difficult topics were a breeze because of Justin's phenomenal explanations. Some of my friends who almost failed Calc 2 last semester got an A in Calc 3 this semester because of Justin! As for his exams, be prepared because they are not easy. But he has all his previous midterms posted on his website, so if you do at least 4 or 5 of them as practice before your exam, you are more or less guaranteed a good grade on the exam. On the rare occasion you might be confused in his class, you can watch his youtube videos in which he goes over every chapter topic in even more detail (and with more examples). - He does not curve because his exam averages are high (range from a 75% to 85%) but he does drop your lowest 4 quizzes and group works, as well as replace your lowest scoring midterm with your final exam (only if it helps your grade). These is a reason his man has almost a 5 star rating with 161 reviews.

Unsurprisingly a great class. Nothing less expected from Justin. Pros: + Outstanding lectures + Reasonable homeworks and coding assignments + Fair exams + Good grade distribution - nothing is too heavily weighted + Responsive on Piazza + Helpful overview of materials, was an appropriate amount of breadth Cons (these are really meant to be constructive feedback): - There were some nontrivial mistakes on homeworks/notes/exams, which wasn't the end of the world, but did cost me time while taking the exam - Some of the Piazza responses could have been more civil Take a class with Justin if he's teaching it!

This was Justin's first time teaching this course and he smashed it. The course structure was excellent and I could tell how everything built on previous content and tied together. I felt we spent an appropriate amount of time on each subject and were able to learn how everything functioned without getting to caught up or rushing through it. I was glad we got the opportunity to touch on hash functions and cryptocurrencies as well as elliptic curve encryption and holomorphic encryption. You could always count on one homework assignment every week with a coding assignment. It was very reasonable and the homework definitely improved my understanding of the content.

Justin has way higher averages on every exam than other professors, so he doesn't curve. however, this is because he makes course content easy to understand. Justin has discussions and quizzes down to a T and it really helped my understanding of the course material. I'm sure you already know this but if you CAN take justin, then you should.

Lives up to the hype! If you're not an engineering/math major though I will say there's a bit of a learning curve when it comes to figuring out how to study and make time for this class. You don't necessarily have to go to lecture because Justin's YouTube videos are just as good, if not better (there are more examples on them since he doesn't have a time limit). But you should because he explains things very clearly and isn't boring. Also has a cool accent. Dropped the 4 lowest group works and quizzes. MatLab projects are super beginner-friendly but I would recommend starting them early just in case you need to work out tiny bugs in your code. They are easy 100s though! For exams, DO THE PRACTICE EXAMS! They are so helpful and he has solutions uploaded for most of them. Couldn't recommend him more!

Justin deserves his reputation as the best UMD professor. He isn't overhyped. In fact, he should be hyped up even more than he is already. His quizzes and exams are challenging, but since he's such a phenomenal teacher, it doesn't even matter how difficult his assessments are because you'll have learned the content thoroughly. He has a gift for explaining things clearly and is excellent at visual demonstration. He makes the course content seem simple because he doesn't needlessly convolute or overcomplicate anything. I pity anyone who graduates from UMD and has never taken a class with Justin. He is a world class professor and must be protected at all costs.

He is very good at public speaking but he seems to not be able to empathize with the students that are struggling through the course. This tells me a lot more about who he is as a teacher than what his lecturing style lets on. To be a good teacher who have to know what it is like to fail and then the endurance needed to overcome that failure and sadly I don't think he understands that yet.

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.

I cannot imagine any other professor has ever taught CMSC351 at the same high level quality as Justin. As someone who took the course with Clyde Kruskal and failed, retaking it with Justin was the biggest blessing in my computer science degree. His notes for this course are so good that I plan on using them for interview preparation and beyond. He made the class exciting, interesting, and erased the dread about algorithms which was instilled in me by Kruskal.

Made arguably the hardest CS class at UMD into one of the most interesting, useful, and honestly kind of easy class there is. Has such detailed notes for each topic that is publicly available (look up immortal umd for his umd website with the links to notes). These were absolute lifesavers and also just demonstrated how much he enjoys what he does, which is another reason why I gave him 5 stars. He is definitely one of the best professors I have ever seen. He is nice in office hours and with questions, but he will come across extremely blunt and sometimes rude in piaza and emails, but he explains that it's the fact he has so many questions and has to go through them. So I was taken aback at first since he seemed a little rude in emails and posts but he is really nice in office hours and just when he is able to actually spend time on answers.

By far one of the best professors I've met at UMD. I was skeptical about joining his class as it was his first time teaching CMSC351 but he went above and beyond during the semester we were learning online. Justin spent a lot of time coming up with online class notes on his own time to explain difficult concepts, and spent a lot of time in lecture going through examples to help clarify content in the notes. Grading and exam timing-wise, Justin was very empathetic and reasonable with students. Do the homework and review his notes before exams and you'll do well in the course!

Justin is great! As long as you do the homework, attend lecture, and review concepts here and there, I firmly believe it’s possible for anyone to get an A under this man. He is prepared every lecture and explains concepts in a simple and clear way. His drawings are neat and really enable you to understand 3-D space. The way the class is setup with group work also helps reinforce concepts. Quizzes and midterms are super straightforward without any curveballs. He is also very approachable and helpful during office hours. Basically, if you have the opportunity to take a class with him, do it. He always shows up as TBA, so check reddit if he’s teaching that sem and sign up!

Justin is the best human being on the planet. As a great communicator, each lecture is planned exceptionally well and each concept is explained thoroughly. He's charming and relatable, and manages to crack some jokes in each lecture. The assignments are easy; the class is no harder than it needs to be. I didn't do any of the optional practice problems from the book and pulled off a 97. The exams are straightforward, just study well and put in the time to succeed.

MATH206 is a great course! Easy 1 credit online class that took maybe 3 hours to finish and a great way to add that you know Matlab on your resume. Most other math courses use Matlab as a supplemental tool where you learn the commands useful for that course but you never actually learn the basic framework. Math206 is a great way to do that. Don't worry about this course, the tutorials are great, the professor is great, the TA is great, and the resubmit policy will make it hard to not get a good grade.

Justin consistently comes to class prepared to teach the material, and his expertise combined with his clarity of instruction enables him to be an excellent lecturer. He is always professional and down-to-earth with his students, especially during office hours. He deserves his consistently high ratings and I strongly recommend taking him when given the chance.

This class was entirely digital and lasted less than half the semester, but I have absolutely no complaints. If you know MATLAB, then the class is extremely easy, and it takes a sum total of three hours to complete all work for the course. If you don’t know MATLAB already, then there is a collection of helpful (and humorous) tutorial documents provided on Canvas to help you teach yourself, and there is a very forgiving resubmission policy to help you out if you make some small mistakes.

I've had Justin for MATH241, MATH401, and MATH410. He's been incredible for all three. He is such a nice guy and simply knows how to each. He also runs his classes in a professional, organized fashion. His expectations are always very clear and his willingness to help students is unparalleled by any other professor I've had at this university. He seems to always know exactly what students are thinking. Because I've had him for three classes, I've seen how he adapts his style to best suit different types of classes. Especially for MATH410, where the material gives students a lot of trouble, Justin is so good at explaining things clearly and patiently. I cannot even fathom the notion that there could be a better professor on this campus than Justin.

Everyone pretty much says to take MATH206, but I'll give a contrasting opinion here. I would recommend to take the class, but be wary of the grading scheme used. The grading scale is: Project 1 - 100 pts, Project 2 - 100 pts, Project 3 - 200 pts. After you submit a project, you have 1 day to fix the project in order to get full points, otherwise you can only get 80% of points. Because the grading scheme is lopsided, I got 100% on the first two projects, and got an 80% on the third project, giving me a 90% in the class. You can't see what errors you have unless you submit the project, so you only have one chance to redo the project. Justin is great at responding to emails, but is fully strict in following what is on the syllabus without leeway.

Honestly, if you're a CS major who's taken 132 or is in 216 or higher, you can pass this class no problemo. It's very very basic coding. You follow the project description step by step, and use the MATLAB pdfs he provides on each topic to do it. I only put in at most 2 hours of work on each project, and he gives you 3 weeks to do each project. Would recommend for easy grade booster, or if you want to know programming in MATLAB basics.

I had him for the online MATLAB course over the summer. I never once met him in person, but for an online class, it was great. He had all of his PDFs laid out and available. They were concise and had plenty of examples. The assignments were overall fairly straightforward, though you may have to think for a few minutes about a couple of the later ones. You get a second chance to get a 100% if your code is incorrect after the first submission, which was a nice bonus. He always got back to my e-mails pretty quickly and did his best to help with any errors I was having in my code just through e-mail. I got a 100% in the class and would definitely recommend his intro to MATLAB course.

One of the best, if not the best professors. He presents the materials in ways that anyone (even with poor background and fundamentals in math) can understand if he/she puts some effort. He tells students what to focus for the exams. TA was extremely nice and helpful as well. Wyss-Gallifent is just a really cool professor. His exams were fair (more on easy side since i falied Calc 1 once and re-took it during spring semester). He's extremely nice guy. When Levermore had a class before us, and left the board messy and ended late (about 2~3 minutes before our class time), Justin never lost his cool. Not even once. Take him.

Tests are difficult enough to let you see if you actually are understanding the material, but not so difficult that you feel like crap after taking them. I also took the MATLAB course. The tutorial was really helpful and clear. I spent maybe 10 hours total the entire semester on this class, and that includes learning MATLAB from scratch and doing the projects. Take this class as early as possible; it's easy, not a lot of work, and a decent introduction to MATLAB.

If I wasn't sure about something, I just emailed the TA, and he made things really clear, so definitely take advantage of him (he's grading your projects anyways).

TAKE JUSTIN FOR ANY CLASS! He is literally the best professor I've had at Maryland by far! He explains concepts really well and he even adds some math humor into the lectures sometimes. Even though calc 3 wasn't always easy, he explained things very well and there was never a moment in class where I felt lost. His exams are very fair if you pay attention in lecture, and do the suggested but optional homework problems he posts online. Definitely go to discussions because there is a quiz at least once a week in discussion. The quizzes in discussions are 10 points each and add up to be 100 points of the total point value of the class. There are also 3 Matlab projects throughout the semester and 1 Matlab quiz, each worth 25 points, also adding up to 100 points. We had four exams in the semester, each exam worth 100 points each. The final exam this year was written by Justin and was also fair, no surprises. Overall, I really enjoyed Calc 3 with Justin and I would retake another class with him if I could.

Great person, even better professor. You don't need to get the textbook, he will teach you everything you need to know in class and dumb it down for the people who really know nothing about math (which is not the best for some people because if you go into higher math later, it is possible that you won't able to deal with some of the complex proofs and derivations since justin's version of 241 is so simplified). Very reasonable exams; he only gives you problems you have seen before. Has weekly quizzes in discussions, four matlab projects (actually 3 and then 1 matlab quiz), four exams, and a final. Nothing is too hard in this class; everyone should be fine.

There were three projects I think. They were pretty easy but last one took a little bit of time to do but was still very doable. I felt like the class was extremely helpful especially since I was taking differential equations at the same time which uses MATLAB. Plus the class is only like three months long.

I took Justin for Math 241 fall of '11, and have to say that he brought back a love of math I thought UMD math teachers had sufficiently killed off in me. Justin is a great math teacher. He is not only approachable but a genuinely nice guy who teaches because he loves to teach. He is a lecturer, NOT someone who is being forced to take time away from their work to teach the class. My biggest recommendation is a simple one. Swing by his office hours and say hello. I found myself practically living out of his office once I started going. It was a great place to get math work done, get extra problems, or just chat, and Justin is a great source for math help as well as random facts and entertainment. In addition to everything I've already said, I want to point out that for anyone afraid of Matlab, Justin's are very reasonable, and his guides will get you through most of them without any problem. Justin is also very fast about answering emails with questions, especially as MATLAB assignments approach their deadlines.

Has about one quiz per week in discussion but they're mostly up to the TA. Assigns three MATLABs where he gives tutorials for all of them so it's basically an application of it and there's one super easy quiz on it as well.

He teaches the class with theory and lots of examples. His notes were so good that I only opened my book to do the hw. His pace with the syllabus is reasonable but faster compared to other professors because Justin wants to spend more time in the latter chapters. Those chapters are crazy so it will benefit in the long run. His exams are easy and follows the sample exams he posts before the exams. There are three easy matlab assignments. The fourth one is a short matlab quiz. All matlab related hw/quiz is easy. The final was not that bad. But do not underestimate the finals. You still need to work hard.

He is very down to earth for a person who holds a PhD. Assignments: 4 exams (none dropped), 4 matlabs (the last was a quiz counted as a matlab to make sure we were actually doing our own matlab assignments), 12 quizzes (2 dropped), and the final. Doesn't really curve grades since the average is usually high for a math course (low 80's).

Weekly quizzes and monthly(ish) MATLAB assignments which he gives a full tutorial for. 4 exams, which is more than average, but it is for good reason, as the last chapter is the hardest, and therefore gets its own test. Curve is very light, 4 percent this year, but class was easy. And you don't really need the textbook. He gives example exams which are close to the real thing, and the discussions help too.

I am going to compare Cremins vs Justin So I took MATH130 with Cremins first. He is not a bad professor at all, but if I had a choice, I would have definitely waited one semester to take it with Justin. Cremins teaches relatively well, but at a quick pace so taking his lectures would be beneficial to you if you took calculus before in high school or somewhere else. His exams are challenging sometimes. If you have never seen calculus before in your life, then take it with Justin. Unlike Cremins, Justin really takes everything step by step to make sure you know whatever he is teaching means and why he is doing whatever he is doing. Justin also puts out sample tests that are pretty much verbatim, (except for variables and etc.) to the actual exams. The grading system he has is also good because you can either concentrate on your exam grades, or your group work, quizzes, and final and take the higher grade. Meaning if you get an overall C on your midterms and get an overall B on group work, quizzes, and the final, you get a B in the class. This is much more flexible than Cremins, where you get what you get out of the entire total of quizzes, mid terms, etc. Justin sometimes writes useless transitions like "lets think about this" or "think about it!" but that doesn't really bother me too much. His handwriting is also very neat, which sometimes Cremins lacks. So in a nutshell, if you have taken calculus before, are really good at math, Cremins is a good choice. If you are not so great at math and want a slightly easier grading policy, Justin's the way to go.

He also gives 2 sample exams prior to every exam that basically prepare you. The quizzes and bio worksheets depend on the TAs, so hopefully you have nice ones.

If you have an opportunity to take him, do it. You will love yourself for it I had him for 130 and 131. They work the same way: -you gotta go to the hour and 15 min lecture. It rarely ever feels that long and he writes EVERYTHING on the board [so spacing out for a few won't kill you]. -one math discussion a week with a 10 point quiz. he only counts 10. there are 13 or 14. win. -one bio discussion a week with an easy 10 point group work. same deal: only counts 10. win again. -you'll only need the textbook for [optional] homework or extra review problems. - he gives one or two sample exams. he gives an ENTIRE lecture before a test as a review day. go to it,do the sample exams, and YOU CAN'T FAIL. This man was born to teach calculus. And he has a sweet accent. That's the formula for a great professor.

I had taken calc1 3 weeks later the previous semester with Okijo *he had a longer name* and i learned nothing in the course. But Justin taught everything perfectly. He did a amazing job explaining concepts and, unlike most professors, started out like you knew nothing. He would explain things that you thought you knew, but he would give you a deeper understanding about it. He is a really cool guy and makes lecture fun with his jokes.If your taking calc, make sure you have him as your professor and no one else. He is hands down the best teacher I've ever had. lol I wish he taught calc 3 lol

I also took Gulick's 140 my first semester here and although he was a great teacher, I still had a difficulty learning and understanding the material. Justin made it really simple and easy to understand. By writting literally every word on the board taking notes was easy. His sense of humor and cool accent are an added bonus!

There's a reason Justin is the highest rated professor on this site: he is the absolute man. I had the privilege to take MATH140 with him this semester and understood the material 10 times better than when I did in high school. He teaches the material with such clarity that it is impossible to not understand what is going on (no matter how dumb you may be). What separates him from every other professor here at UMD is his teaching style. He is incredibly fun and engaging with the students. He always goes off topic with a joke or random topic at least once per class and it just makes you think to yourself "this guy is so cool." This may sound like a strange love story, but I guarantee you that if you take this class (or any class) with Justin, you will feel the same way. One day I saw him walking around campus in his red converse sneakers enjoying the awesome weather outside and I feel like that sums up who he is completely: the best professor I've ever had. Thank you Justin!

Justin is a really great professor! His lectures are really easy to follow, and actually makes the lecture a little more fun. He does everything in a way that is really easy to understand, but even if you still can't grasp the concept, he is always willing to talk to you after lecture, at office hours, or whenever. You still need to study, but most of the time, a lot of the problems are right from the old exams, or from class problems. I would recommend Justin to anyone who needs to take a math course.

I took Gulicks 140 and failed with a D. He is by no means a bad proff however. He just doesnt teach it the way Justin does. Justin thoroughly enjoys the nuances and implications of what he teaches and puts everything in terms that non math majors can understand. He starts with a non proof driven explaination and follows it up with the reasoning/proof. Drastically simplifies the overwhelming material in the book. I have not opened it once this semester. every question i've had could be answered by my notes. Ive definately needed to study for the exams but my work has been rewarded. The exact same amount of work in Gulicks earned me a D but i fully expect an A or B+ this go-round.

Single best professor that I had last semester. I cant really add much beyond what the other reviewers have said. He is just truly that excellent. He really made math fun, and the only way that he could have made the class easier was to take the exam for you. Beyond that, he really explained things well, so that the stuff that I learned in AP Stat and AP Calc finally clicked into place and made sense in the context of the world.

Abstract Algebra was probably the most difficult course I have taken so far in college, but it was all worth it because I learned an incredible amount thanks to Justin's awesome teaching skills! I had him for 246 last semester, so I decided to give this class a try because he was teaching it. 403 was a very tough course for me, but I'm sure I would have failed the class if any other professor had taught it. Justin lectures is such a straightforward, easy-to-follow manner and explains everything he writes of the chalkboard. He provides plenty of examples so that everyone can comprehend the meaning of theorems, definitions, and proofs he writes on the board. Unlike most of the professors in the math department, Justin actually cares about his students and doesn't brush them off. He responds to emails very quickly and has numerous office hours available if you need extra help, since many of us did need it. The exams were pretty hard, but straightforward nonetheless, with averages/medians usually in the 50s. He does give an appropriate curve so if you think you're failing, don't worry, all hope is not lost!

Justin was an amazing teacher. He took the time to explain things to you in an engaging way. His lectures were never boring and they never seemed as long as they really were. He always uses real life examples relating to our field of study so that we could feel as though we were actually learning something. He not only teaches you how to do something, but often teaches you why you are doing it that way and how the formula was derived. His tests were very straight forward and closely resembled the practice exams, so you always knew what to study. He was an amazing teacher who really loved to teach. He also computes your grade two different ways at the end of the 131 course and takes the higher of the two grades. I highly recommend taking Justin's classes, you won't regret it.

Justin is a fantastic professor. He is extremely knowledgeable, but teaches in a format that is conducive for all students to succeed. He is extremely fun and all students actually enjoy going to his classes. The workload is perfect and his tests, quizzes, and group works couldn't be more fair. He is ALWAYS available for help outside of class. He is the best and funniest professor I have ever met. TAKE THIS CLASS. I promise you that you will do amazing (if you work hard) and you will actually want to go to class. Justin clearly cares about all his students and I think the good ratings below me vouch that he is an amazing professor. He gives sample exams to help you prep for his exams and he drops 3 quizzes and 3 group works. The homework is good practice for the exams so I really advise you do it. However, it is not collected/graded so it is not mandatory. My only regret is not failing this class so I could take him again!!! Overall, the best professor UMD has!

Justin is by far the best teacher in the math department. He covers everything you need to know in depth and focuses on things that each class is having trouble with. He takes it personally if his class does poorly on his exams and really puts in the effort to make sure they don't. That being said, his exams aren't easy but aren't impossible either. If you do the work and go to class you will do fine.

Justin is a great professor. he doesnt make you learn all of the unnecessary things that the other 246 teachers make you learn. his tests are basic and there is nothing that is on there to try to trick you. they are basically the same as the practice tests he gives, which really help a lot. the final exam was a little bit more difficult because it is a uniform exam and there are things that he did not cover, as far as i know. (i did not go to many classes at the end of the semester) he probably would have curved it, but he had taught the other material so well, our class did better than the classes who covered more material. Overall, if you put any effort into this class, there is no reason to not get an A

Justin is a great professor. MATH246 is a very hard class, and the book they give you is not very good at explaining, so lectures are very important when learning the material. He was pretty flexible with missed MATLAB assignments, which were pretty frustrating. Additionally there are weekly quizzes in discussion but he drops a few of them. I missed many lectures and quizzes and still have a chance to get a B. As long as you go to lectures and take all the notes, you will have no problem getting a good grade in Justin's class.

By far the best math professor I've had. If you go to class and write down all the notes he writes on the board, the only time you will open your book is to see what the homework problems are. Lectures are very organized, starts with the theory and then shows a couple of examples. The best thing is that he only teaches what you need to know for the tests and the tests themselves are really easy. He doesn't try to trick you with the tests and the sample exams he gives are very similar to the actual tests. Basically, if you can do the sample exams you will know how to do the entire test. Weekly quizzes are a pain, but he only takes the top ten. MATLAB is similarly a pain, but he posts guides to the MATLAB assignments that are pretty much a step by step guide to the problems. If you can, take Justin for any math class that you have to take.

Amazing professor. Is very approachable and teaches in a very relaxed and fun style. Always welcomes questions in class and attendance at office hours.

Analyze the sample exam questions and try to think of ways of re-phrasing the questions as some of the actual exam questions can be a bit tricky. Write down everything he says in lecture and you'll never need to open the book except to do homework problems. Studied right off of my class notes.
