Not the best lecturer, but exams are pretty doable compared to other professors. Take if you want a decent professor for math

I enjoyed his lectures, surprisingly. He is a good professor although i found his tests a little hard but if you do the work you will be fine. All around nice guy however still curious as to what is in the jar that he always has with him.

Really brush up on your algebra, trig tricks, and you will do well not only in calculus 3 but all calculus courses

He was very good at teaching the material, and did examples with the class, as opposed to simply doing them before we had a chance to solve them ourselves. Even when the material was somewhat slow, his sense of humor managed to keep me paying attention. The workshops always had hilarious footnotes and his emails made students laugh a lot.

Molnar is great at teaching but gives difficult tests. He has a good personality and is very interested in the topic. If you go to his lectures you will learn from him. As for most math classes there is plenty of homework and quizzes in his class. If you attend lecture and prepare for tests you will be fine.

He was both entertaining and informative in his lectures. The material itself was interesting, but he presented it in such a way that it was easier to visualize and really understand. His humor absolutely made the class so worthwhile, too. I'm trying to take more classes with him! PS. do figure out the contents of the mason jar.

great professor, if you go to class and take notes you will do fine, tests tend to be difficult yet fair and he curves them fair

Solid professor, but don't expect to pass unless you put in effort. His lectures will prepare you for what is to come for the exams, but you need to put in significant work into the class outside of lecture if you want to do well. Took him for 251 and 244

He was extremely difficult in the beginning of class, but I was easily able to adjust to his teaching style. He loves to give notes, but they're super clear. You just have to give him your full attention in class and do all the homework he gives thoroughly. He gives a lot of practice problems so that should help. Also, office hours are great!

great teacher, cool dude. if you get the chance, take his courses. makes material easy to understand while somehow keeping lectures interesting.

Molnar is the best lecturer I have had so far at Rutgers. He explains topics very clearly, however his exams are hard. Expect averages to be in the 30s - 40s range.

Molnar is a really funny and helpful guy. He really wants everyone to fully understand the nuances of calculus theorems. With that being said, his exams are VERY tough and the average for midterms 1 AND 2 were both 39. However, I felt a much larger drive to really study hard for this class and I feel like I benefited from having Molnar and his jar.

I am shocked to see the reviews. For me, he was the best mathematics instructor I have ever had! Amazingly clear and entertaining lectures. If you do all of the recommended book problems and Webassigns making sure you really know how to do them, and memorize all that is asked to be memorized, the exams will be a breeze.

Really clear, engaging lectures. He is hysterical and does everything he can to make it enjoyable. The 2 midterms were INSANE but he was merciful on the final. Overall, I liked it. I think any Calc 3 class is going to be crazy hard, so you might as well take someone fun.

Prof Molnar gives a really clear explanation and neat notes. If you got thing confused, go to ask him, he will be very helpful and kind towards students.

Great Professor and what a wonderful way to learn, would definitely take again

Currently am taking Calculus 3 with Prof. Molnar. He is a solid lecturer, meaning he is clear and will take the time to answer any questions so do not hesitate. My only concern is that I have weak background in calc 1. He usually assumes you know certain things, which is understandable. Make sure you have strong foundation before taking.

He is the greatest PROFESSOR I've ever met. EASY quizes, EASY Exams, ands EASY A.

Ok he is a decent human who does his best to be interesting. Workshops were difficult, 5 maples throughout semester, and a couple quizzes. You need to review a lot to succeed. He clearly knows his material so ask questions. Study a little everyday. Go to office hours. His tests are tough so in order to succeed you must practice a lot.

Fairly entertaining lecturer. I thought his lectures often went through problems much more difficult than on the midterms or final. I also overestimated the difficulty of his exams; I'd end up overpreparing and do well on the exams. The curve is very generous. There's webassign/maple/quizzes/workshops, but they count nowhere near as much as EXAMS.

Good lecturer, doesnt make it boring and is helpful during office hours. However, his methods of running things are somewhat questionable. He doesnt give homework outside of workshops and quizzes while not giving solutions to suggested problems. Also, he doesnt give averages so you dont exactly know how youre ever doing in class.

Professor Molnar is the best Math professor I have ever had. i took him for both Calc 2 & 3. he's really funny and holds interesting lectures and is willing to help his students. ask him questions if you do not understand anything because he's clarifies stuff better if for you ask. his exams are fair if you study and do his practice problems.

Professor Molnar was great and explained things clearly, I learned a great deal from him. HOWEVER, his exams are EXTREMELY hard and you have to work really hard to do well.

A good teacher, but quizzes and tests are harder compared to other 244 classes.

amazing class ! took differentials with him over summer and learned a lot. he gives you a quiz outline with what will be on each quiz and there was no online homework- which motivates you to do the problems yourself. he tries to have fun and the exams are hard but theres always a chance for redemption as you can earn extra points on the exams.

His class is really difficult, but a nice person

His tests are difficult but definitely passable as long as you keep up with the homework and take the time to understand the concepts. He's quite funny and his lectures are very helpful to understand difficult topics.

I had Professor Molnar for differential equations last summer. I really enjoyed his lectures; he explained everything clearly and concisely. Homework was optional but the problems were helpful and he would go over any questions the next day in class. Tests were fair. Probably one of the best math professors I've had.

Molnar was my favorite professor this semester. He makes his own notes and interacts with the class through chat a lot. The material is hard, but Molnar at least made it a little fun to learn. He adapted to online very well. His quizzes can be a little difficult. You need to work for the exams, but it is def not extremely difficult to do well.

The class worked well, despite the fact that I took it online. Professor Molnar has a good sense of humor and makes class entertaining. There wasn't that much time for going over a ton of examples or the proofs that support the concepts, especially towards the end of the class, but it's enough to work with. Very prompt in responding to emails.

I dont understand why people rated him so low. He is a great professor and I really like his lecture. It was fun and helpful. If you do what he tells you to do your grades should be garenteed above B

He made a very time-consuming class a little less tedious than it could have been. His lectures are entertaining, and while I wish he had enough time to go over proofs in the latter half of the semester, the ones he did do were very interesting. His weekly quizzes were occasionally difficult, but usually fairly reflected that week's lesson.

His humor is dry and sarcastic which is absolute gold to me. His lectures can be a bit dry so I mostly relied on the textbook and then quickly going through the recorded lectures. The best part of him is that he clearly wants his students to succeed. His office hours are great and he makes sure you have plenty of resources.

I took Molnar for both Calc 251 and 244 and really liked his classes. He tried to get people involved in the online space and made the material fun to learn through amusing questions. While his class was by no means easy, he is great at explaining and a really good option for a good, hard class.

My favorite prof of all time period

Diff Eq with Molnar is a tough class - but I think that's mainly because there's no mandatory homework compared to Calcs 1-3. You need to practice on your own with the recitation sets (which are hard) and textbook problems, and then you'll be set. He is tough when giving partial credit on exams. Most of the practice material doesn't have solutions

251 is a hard class, but Molnar is a funny guy and a pretty good lecturer. He is helpful in office hours. He gives you many resources to succeed, especially practice exams. His weekly quizzes were of medium difficulty. He also gave practice problems in recitation, but they were harder than anything else. Overall cool guy. Just don't fall behind.

I did not mind Professor Molnar, his weekly quizzes were not that bad if you understood the material, I really liked his lectures he was a funny guy. His tests were alright, the review material was decent practice. You should do the recommended problems he gives during lectures that helped a lot while studying. Overall, great professor.

Hes a great prof. He explains the material well in his lectures and answers questions with the perfect responce. He is funny and almost acts like a clown a bit. Not in a negative way. However, u gotta review the material every day cause u will forget it. Recitation is a lot of work tho, hw takes a while. Excellent prof but a lot of work

Prof Molnar is one of the greatest math instructors I have ever had in my entire life. His humor really added to the lectures and although this class required a lot of work I always felt that the recitations were based on things that we directly learned in lecture. The final was easier than his midterms, which were based on textbook problems.

Professor Molnar is a good professor with straight forward exams. He will give you extra study material and has a good teaching style. Lectures focus on practice problems.

W professor

Molnar is a pretty good lecturer, he explained the topics in a very straightforward way, even though he did go off on some tangents in a few lectures. You do have to put in the work to do well in this class. Make sure you know how to do EVERY PROBLEM from workshops and lectures before exams.

W professor round 2

Very good Professor, has a funny sense of humor and teaches very well. He is a tough grader on tests.

David Molnar was an amazing professor.

Prof Molnar is a fun, incredibly smart teacher. He will make proofwriting less abstract and more straightforward. It is certainly challenging and demanding but practice and learn from the feedback on exams and quizzes. quizzes are like workshops, but exams can be a bit more strategic (note that I didn't say difficult).

Good professor overall; if you go to most of his lectures, you will be well prepared for the exams. Most problems on the 3 midterms and the final were doable with the exception of a couple hard ones. If you do the online HW problems on Pearson, textbook problems, and practice exams from previous years, you should be able to get at least a B.

Molnar is a great lecturer but his section is extremely difficult. He grades very harshly and the midterms are much more difficult than other sections. This does prepare you for the final and he curves in order to account for the added difficulty. I ended with a 68 which was considered a B. Also, this is a class you should 100% go to lecture for.

DM is a great guy. The course material was tough but he manages to make it digestible. That being said, Calc2 is still a very hard class so you should still study on your own. DM's office hours are great for this since he can help you understand concepts that might not have been best explained during lecture. Would definitely take him again.

Inspirational. Respected. Hilarious. These three words describe Professor Molnar to a T. Prof. Molnar didn't just teach - he ignited a new passion for my studies. If you need a prof who will inspire you, challenge you, and change the way you see the world, look no further. This isn't just a class - it's Professor Molnar's investment in your future.

DM makes Calc at Rutgers interesting with his sense of humor and the jar. But seriously he is really good I would recommend.

While Math 251 is notoriously challenging, particularly the last third of the material, I found that Molnar explained the topics well. The workshops and quizzes he gave were relatively challenging but his exams were more straightforward.

Very cool class.

Awesome professor. Great teaching style and very easy to understand. Super accessible and truly wants you to understand the material. Class is difficult but its the material and he makes it as easy as he can with his explanation. If you go to lecture and actually listen to him, you will do well.

tough grader, but funny and very willing to help if you reach out to him outside of class. you have to work pretty hard for your grade and going to lectures makes the class much more manageable, but molnar is one of the most honest and helpful profs i've ever had

David Molnar is the GOAT for Calculus 3 because he makes complex topics like multivariable calculus and vector fields clear and engaging. His step-by-step explanations and practical examples build confidence, while his dedication to helping students succeed—through extra support and encouragement—fosters a deep love for math.

Calculus 3 is fairly straightforward until the last chapter (and to be fair I hadn't attended the lectures for those sections, I just read the textbook). Professor Molnar taught calc 3 with a high level of clarity, provided good lecture slides, and I found the pearson homework, while tedious, to be helpful. If you were fine in calc 1, you'll be ok.

Good lecturer and was very helpful when answering student questions. Lecture attendance not mandatory, although I would strongly recommend it. Recitation attendance is mandatory due to having weekly quizzes. Towards the end the material gets challenging, but Molnar makes sure you understand what exactly you need to do depending on the question.

Math 251 with Professor Molnar is no easy feat, but his engaging lectures and challenging workshops pay off. The exams are tough, but with the help of unstuck AI and a committed work ethic, you can succeed. Definitely worth the effort.

Were the only lectures I went to and paid attention in. Gives exposure to many different topics e.g. combinatorics, analysis, game theory. Good for the mind, not as great for the gpa

Good professor and teaches concepts pretty well. Usually gave a 1-2 question quiz every week; these quizzes got harder after the first midterm. Midterm exams were pretty difficult and so was the final. Some topics were interesting but class got harder as the semester progressed. Also gave reasonable amount of HW. Lot of effort required to get an A.

He is very cute. Usually likes to include emojis in his PPT, make the class funny. In his office hour, he makes jokes, feels very close to students! He never misses any class, each class is fully prepared we high high-quality lectures.

I really didn't attend any of my classes except for this one. Very engaging lectures and problems. Every question (including on exams) was very fun to work on. There's definitely easier professors out there to get an A in. But if your goal is anything else, take Molnar.
