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.

Justin Wyss-Gallifent is a god. No one shall attempt to defy Justin Wyss-Gallifent. You shall say Justin Wyss-Gallifent's full name when referring to him or else you'll be punished by Justin Wyss-Gallifent himself. It is said that even Chuck Norris has kneeled down to Justin Wyss-Gallifent. Take Justin Wyss-Gallifent's class to succeed and learn Math. Justin Wyss-Gallifent has already taken his own gracious time to step out of heaven to teach math to plebeians like us. Please consider his time and efforts.

Best Math professor I've ever had at UMD, hands down. If this guy is available for any Math course that you are taking, ENROLL FOR JUSTIN'S CLASS. You will definitely not regret it. He teaches in such a clear and precise manner, and he is also a very nice guy that is willing to help you after class. He genuinely loves to teach to students, and it really shows.

Justin is one of the best, if not the best professor I have had at UMD. He always comes in prepared, and since he has been teaching this class for years, he knows and stresses all the places where people tend to make mistakes, so you won't make them. He has a step-by-step approach to solving every problem you will run into. In addition, he is also very kind and makes jokes throughout the lecture. If you ever have the chance to take him, do it. I promise you won't regret it.

Didn't think he would live up to the hype, but goddamn, he did. I took Math 206 with him and sat in on his Math 241 class, and most of my experience with him was for 241. I had already taken 241 in high school, but I felt like I learned the course entirely anew. Incredible, incredible guy. He reminded me why I pay for college. If there is an option to take your class with Justin, work the rest of your schedule around it. Make this a priority.

Justin is awesome! I had the pleasure of him being my TA as well as lecture teacher. He is by far the best math professor I have ever had. He is understanding about making up quizzes, and makes his lectures interesting. He wants his students to do well. Justin answers e-mails so quickly, and can always provide helpful answers. He always gives 2 study guides with the solutions for each exam. His exams were all fair. Not easy, but everything that was on the exam was thoroughly taught. I can't stress how awesome of a professor he is.

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. If you put in a little bit of effort, you're gonna pass.

Justin is a little overrated as a professor, but he's so highly rated that that still means he's awesome! He's cool, he's funny and he's an engaging speaker. You'll come out of the course really understanding the material and his tests aren't super easy but they're very straightforward and lots of practice tests let you know what to expect. If Justin is available TAKE HIS CLASS!!!!

He really cares about his students. He explains concepts extremely clearly and encourages you to think about what's going on in class. I never had to use the textbook because his notes are so clear. 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.

Justin is more or less the ideal math professor. Energetic, engaging, and interesting, his lectures proceed at the perfect pace with exactly the right balance between examples and theory. Just take him already. Think of a complimentary adjective that could apply to a professor and it probably applies to Justin. Seriously, if it's a choice between Justin and someone else, it's not a choice. Justin all the way. Why are you still reading this? Go to Testudo and register for his class already.

Justin is amazing if you don't already know. I had him for calc3 and he was boss. My review is more for the Matlab course. If you need a GPA booster, take this class. Justin is really helpful, and provides awesome tutorials. Also, the TA is amazing. 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). There are only three projects and Justin gives you a lot of time to do them. The last project is a little tricky but the TA offers a lot of guidance. Take this course, you won't regret it.

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.

MATH206 was a very easy class. There were 3 online project using matlab, and all of them are posted on the first week, so if you finish all of them, you're basically done. This is an online class so you never actually see the professor, but the T.A.'s are very helpful, and Justin's online is very interesting/easy to read and understand.

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.

Never actually met him because this is an online course. But it was a great class. A great introduction to MATLAB. He explained things on his website very clearly and had plenty of examples and practice problems. He was also always willing to answer questions through email and was very respectful. 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 highly recommend the class.

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.

Justin is hands-down the best math professor I have had at this university. He knows how to explain the topics without confusing the class with worthless proofs and MATLAB.

One of the best teachers I've ever had in my life. (Possibly this will hold true for the rest of college!) He writes precise notes with great handwriting and pictures and explains topics in great detail. Doesn't grade homeworks but they are helpful! 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. Four tests and a final and his tests should be easy since you get a cheat sheet as well

This guy is clearly THE best professor you can have at UMD. Also, for a guy with PhD, he is really humble and really laid back. His notes are very clear and organized. 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. Do not miss out on taking a course with Justin.

Prof. Justin teaches the material by going step-by-step through each example and he even goes over examples of harder problems (which other profs rarely do). 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).

Good teacher. He explains concepts well and goes at a reasonable pace. Lectures are primarily example driven, which makes concepts easier to understand. 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 didn't buy one and got an A.

Justin is a fantastic professor, the best I've had so far at Maryland. He is really engaging and he makes the class understandable and manageable. His tests are straightforward and easy to study for, as many of the questions are modeled off ones from practice exams posted online. He covers a lot of material in every lecture, but not so much that you ever feel overwhelmed. As long as you put in the necessary effort, this class should be no problem.

Really good teacher, especially compared to other math professors at UMD. One of the things I love about Justin is that he is humble. If he felt one of his lectures wasn't perfectly clear, he'll spend some of next class clarifying the tougher bits. Many professors just move on and leave the stragglers behind. I'm not a huge fan of the group works, but they're fairly infrequent. He grades very easily on them because they're tough. Plus he brought us bagels!
MATH130

Anonymous 03/31/2011
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.

I took this course with Cremins in Spring 2010, but got a D so had to retake it. I wish I had taken it with Justin in the first place. Justin writes out his notes neatly in 4 columns on the board, so that they are easy to understand, and when you go back to study your notes everything makes sense. 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. I absolutely loved him, plus I think I was motivated to go to his lecture because of his accent.

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.

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.

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.

I am certainly not a math person, but I actually did really well in Justin's class. He was such a GREAT teacher. Studying for exams was very doable because he always gave practice exams so you knew what to prepare for. He was also hilarious in class and just an all around nice guy. DEFINITELY take him if you can!!

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. Try to get Justin as your prof if at all possible.

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!

Highly recommended. Justin is one of the best professors - funny, engaging, and organized. He teaches in a way where even the most struggling student can understand. He takes everything step-by-step in a very organized and simple way. I did not even have to look in my book for help once. The only time I opened the book was when I was doing the homework problems. Also, the sample exams are very similar to the actual exams.

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

Great class. Exams were like the samples. Screw the MATLAB book...guides were always posted. Excellent professor who broke MATH246 down into the simplest of terms. As long as you do the MATLABs, do well on the exams, and take a decent amount of quizzes, you have the A on lockdown. The final was VERY similar to the ones on testbank.

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.

The best professor I have had at UMD. If you are taking 220, you need to have him. He teaches the material so clearly and what he writes on the board is what you need to know. My roommate and I took 220 at the same time, and with his professor (one of the authors of the textbook) he suffered a lot and did so much more work. The webassigns are tough, but he dropped your 4 lowest ones. He is known to be the best 220 lecturer. I got an A+ and I know 5 other ppl in my discussion did too.

I never figured a calculus class would be my favorite class, but Justin is awesome and I was pleasantly surprised.

Explains everything in details. Instead of forcing us to memorize formulas, he taught us how to derive them. His notes are so good, you'll understand everything without even open the textbook(btw, I suggest the math department make copies for the hw problems on the textbook only for Justin's class. So that we don't have to spend so much $ on a piece of brick). Justin is great, and I completely agree with the person who said "i once was lost but now am found!" ......

He doesn't regurgitate the textbook to you at all. You just sit in his lectures and the material will just seep into your brain.

One of the best math professors at UMD. He did a wonderful job explaining the material to us and was more the willing to help us whenever he could. Like other people said, write down the stuff he writes on the board. It's enough info to study with. The textbook you use is crap anyway, so don't rely on it. We didn't even have to address him formally, he just told us to call him "Justin". He's so cool. I wish he could teach all of my classes. The material for MATH240 is still quite difficult, however. You have to pay attention and do the assigned homework. But Justin will help you as much as he can. TAKE HIS CLASS WHENEVER POSSIBLE.

Amazing professor. Is very approachable and teaches in a very relaxed and fun style. Always welcomes questions in class and attendance at office hours. He posts sample exams for each exam in the course. They're similar to the actual exams, but not verbatim. 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. I would definitely recommend taking a math course with him.

Go to the Lectures and just write down everything he writes even if you aren't paying attention because you will be able to read the notes and understand exactly how to do everything. Make sure you look at the homework every once and a while because he will explain the concepts so well that you will understand the problems in class but then when it gets to a quiz you might not remember. He also makes MATLAB simple and easy, you should have no problem with matlab even if you hate it and if you do, email him and most likely he will give you a hint.

Amazing professor. I had a really good Calc teacher in High School and his teaching style was very similar so I had no problem with the material. He is very detailed in his lectures, and probably is the only math teacher who writes full sentences on the blackboard. The intense detail can get a little boring sometimes, but I would prefer that than a quick overview and then not understand what he's saying. He has a great sense of humor and is very upbeat. I highly recommend his class.

Really good teacher but it was soooo elementary at times. I guess thats why the course is elementary calculus. Its good if you don't understand math at all, but can be kind of pointless if you do. His tests are exactly like the review sheets, if you can understand them, the tests will be a piece of cake. Also drops like the lowest 7 webassigns which was amazing!! Worst part about the class was discussion, the hardest little quizes ever, maybe just my T.A.
