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.

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 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.

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.

TLDR: If you don't have calculus background, take Math 31AL instead.

I apologize if this is long.

The class material itself will not be as complicated BUT ONLY IF you have taken calculus before (Pre-calc, Algebra 2, AP Calc AB). However, this professor is really passive aggressive, fast-paced for who knows what reason, and did not want to help me because "the TA's know." During the first few lectures, it seems as if things will go well. Quizzes look like examples from class and discussion worksheets. They took place in discussion sections and if I had studied better, I would have done better. THE TEXTBOOK IS ALWAYS HELPFUL. I found myself understanding the textbook more than his lectures because I was reading at my own pace. He allowed an index card of notes for the midterms and one side of a sheet of paper for notes for the final.

But the exams.... what was even going on.... Some problems made no sense, but this may be my own fault for not being able to interpret them correctly.
I hated the exams because I was always stressing about how to word my answers and how to properly show my work. He wanted specific ways to show that you really got the answer. It was annoying.

When I went to office hours, a week before finals, I wanted to ask for help while he was talking to a student who was also in the same class. I had asked a question regarding homework and studying, but he told me that the TA knows. Yes, they know but I would not be at office hours if I did not try contacting them. My TA was one of the worst. He did nothing but be on his phone during discussion after passing the discussion worksheet.

This class was one of my first classes as a freshman and I hated how bad I did. I RECOMMEND MATH 31AL INSTEAD. It is the same class but with more discussion sections. It is better equipped and suitable for someone without calculus background.

I'm a math major, and this class was without a doubt the easiest math class I've taken in my three years at UCLA. The professor is super organized, so the lecture notes are always posted to Bruin Learn immediately after class, and I would say you could probably get an A in this class just by reviewing lecture notes and never actually attending class. The homework and exam problems are very similar to example problems provided during class; I don't think we ever got any surprising questions/concepts on assessments that we had not seen before.

This is a review for Math 151B. This class is taught very differently from Math 151A. The professor teaches fine but the exams are very difficult and class average is very low. Without extra credit opportunities the grades for this class would be horrific.

Worst Professor Ever! If you’ve never taken calculus, do not take this class! Hard to understand. Tests were difficult. Allowed small cheat sheet, but didn’t clarify what was on tests.

Besides being an 8am, this class was not too bad. Having some prior knowledge of calc (AB or BC) definitely does help but is not needed. Prof Wumaier did a really good job of teaching the materials and it definitely connected to the homework. Both the midterms were almost identical to the practice midterms he gave out prior, so make sure to do those. The discussion sections are optional (and they did not help me too much) but quizzes do get handed out in discussion so make sure you know when the quiz dates are. His office hours were helpful to an extent. But overall, this class is a good place to start for math.

I took calculus in highschool two years before taking this class so I was familiar but rusty with the material. If you're completely new to calculus, this class can seem very difficult. The professor is fine but he moves fast. Lectures are a must; he generally teaches pretty well. Class was made up of weekly homework, discussion quizzes, midterms, and a final. Homework was kind of annoying because he'd had everything due on Friday night and sometimes wouldn't teach the necessary content until the lecture on Friday morning. I had a great TA who taught during the discussion so I did well on all the discussion quizzes. The quizzes and midterms were easy to moderate in difficulty. The final was moderate to hard. I missed points on the final because I didn't know the proof to Riemann's Sums so make sure to study everything, even the stuff you don't think you need to know. Overall, class was okay.
