I have always been adept at and enjoyed Math; nonetheless, I could see how a person who has never taken calculus before or who has never done too well in Math could struggle. Although Professor cares about his students (he organizes review sessions, is super helpful during office hours, solves a lot of practice exercises, etc), he explains the material in a rather superficial way (I don’t blame him, as there are only ten weeks available for him to do so). So if you have never been the best math student, you are going to have to put some extra effort to understand the material (the professor is super willing to help) and do well in this class.

I had already taken calculus in high school, and I still struggled a lot with this class. The exams made up the entirety of our grade, and the two midterms were too difficult to finish in the 50 minutes allotted. 8 AM class time also definitely didn't help. If you get the chance, don't take 31A with this professor.

if youve never taken ap calc or any other calc class then do NOT take this class. i took ap calc bc in high school so i was lucky enough to understand. the prof kinda expects you to know some of the topics so he never really went into detail with the examples. the examples he did in class DID NOT match what was on the midterm/final. he did offer extra credit during office hours tho but that was only towards the end of the quarter. this class was overall ok since the homework/workload was manageable but i do not recommend.

I don't have massive issues with the class or the professor, but I do think the exams this year were a little more difficult than they needed to be. Other than that, the structure of the class (homework, discussions, etc) was pretty good. I took AP Calc AB in high school, so a lot of the material was review, but I know the pacing is a little fast for those who are new to calculus. If you're taking this class, make sure you study the hardest homework questions for the exams and find additional review for your weak points.

I would take 31A with Professor Wumaier again. His lectures were straightforward and clear; he mainly derived theorems and worked out practice problems in class. He posted blank notes before class so students could print them out/download them before lecture.
Discussion work was fairly simple. Each discussion we were given a worksheet to complete by the end of the week. For discussions close to exams, we were not given worksheets and TAs just went over practice problems.
Homework was assigned through Achieve. Overall hw was not incredibly time consuming. There were probably at most three homework modules that gave me trouble and took a while. Hw was due at the end of the week. I will say that most of the content on the hws does not show up on the exams.
Exams were very fair. Professor posts practice problem sets and a practice exam and holds a review session. The exams were very similar to the practice exam.
Professor Wumaier is very helpful during office hours and offered a lot of extra credit. He was incredibly generous with grading at the end of the quarter. He added extra credit, dropped the lowest hw/worksheet, and decided whether scheme 1 (final worth 39%) or scheme 2 (final worth 54%) would give a better grade.
In all, 31A with Professor Wumaier gave me a good foundation in calculus and the workload and difficulty was reasonable.

I honestly really enjoyed this class. Professor Maimaitiyiming goes over the material clearly and in depth, in my opinion. The class is a bit fast paced, but that is honestly just how it is with the quarter system. He gave a lot of opportunities to ask questions and always answered them in his office hours. In his office hours he also gave extra credit opportunities, which were helpful if you needed the extra boost! Exams were similar to the practice exam and somewhat similar to the practice problems and you should be fine if you understand the concepts behind everything.
I personally thought the book was helpful especially since it allows you to go at your own pace when reviewing materials! i also found it helpful to do a lot of the practice problems in the book.

He was very kind in terms of understanding that we just came out of two years of virtual learning. He gave opportunities for extra credit and had a very generous grading at the end of the quarter (he originally didn’t give us the generous grading changes but without telling us he did them anyways lol). He doesn’t really curve since the grades always averaged to about a B overall, but he did do things like extra credit or dropping the lowest assignment or midterm. Not sure if he will do that next quarter but he is very helpful in office hours and I’ve heard that emailing him is pretty quick too. Would definitely recommend!

Professor Maimaitiyiming was very fair and incredibly nice in lectures. I am pretty sure this was his first quarter at UCLA but was still great in my opinion. He had 24 hour take home exams that were difficult and made to really test if you actually learned the course rather than regurgitating what you saw from the practice problems/tests. If you put in the work, you will do great in this class. Math is not my strong suit but I do think succeeding in this class is very doable.

Definitely a fast moving class, but the professor explains well. Remember to keep an eye on homework assignments, as they aren't always well communicated.

I took Dr. Wumaier's class in the Fall 2020 Quarter, and he was a really great professor. He gives very engaging lectures and he always answers any questions both during lectures and office hours. The textbook and the Sapling assignments were really helpful and I recommend him to anyone who's thinking of taking his class!
