A lot of the difficulty in this class is centered around Analysis just being a really tough topic. Homework was tough, and Professor Wu also did not record any lectures (or post his notes as he did his entire lecture on the chalkboard) so attending lecture in-person is a must to be successful. However, he posted lengthy PDF notes that served as both a textbook / lecture notes that were helpful, as exams were directly based on proofs done in these notes and homework. Exams were on the easier side, since they modeled the practice exams almost entirely. However, a practice exam was not provided for the final, which made it more difficult. Ultimately, I would recommend taking this class with Professor Wu given the exams, but it will still be a difficult class.

This class was the first math class I took at UCLA. I thought that it was a pretty good class, as the teacher was very thorough with his work. Furthermore, the TAs would have a weekly discussion which helped solidify the information learned through the week.

The tests were difficult, however some of the questions would be extremely similar to the ones on the homework, which was helpful. To clarify, he would give you a homework set with around thirty problems, but only a handful of the thirty would be required to submit within that homework. He would then take some of the examples from the thirty problems and use them on the exams. He would also drop one of the two midterms, which was great as the second midterm seemed to be much easier than the first.

I’m not sure why there’s lot of negative comments because Wu was a great teacher. He constantly asked for student feedback on how to improve and had a Piazza discussion page where he answered all questions. It also helped that his TA William Chang was amazing and super helpful. Wu’s lectures were straight forward for the most part and his homework was super easy. His midterm and final were also questions from the notes and homework so as long as you studied using those you should have done fine. I basically self studied using his lectures and found it to be really easy to understand even though J had never taken Calculus.

Wu is not as bad as people say. He is very accommodating and listens to students’ feedback regarding his teaching style. Homework’s are SUPER easy if you just ask him how to do it on Piazza. He responds super fast and will go through the whole problem you need help on and even give the answers. My advice is to do ALL of the homework problems (even if they aren’t submitted for grading) and ALL of his notes’ examples because he literally just copies and pastes the exact questions onto tests. We had a cheat sheet for the final, so I just copied down homework problems/note examples I had trouble with, and i literally just rewrote what i had onto the final. But our saving grace of this class was the TA William Chang because he would post all homework solutions and host review sessions. It may be more difficult if you don’t have a TA similar to him.

For context, I took both AP Calc AB and BC in highschool and this class made me question whether or not I even had a solid foundation in AB. The tests are unnecessarily difficult and his lecturing style is very hard to follow. It was very different from the Calc AB I learned and mastered in highschool. I would not recommend this class to someone who has never taken Calc AB, and for those who have and are retaking it, I would suggest you enroll in another class.

Wu was good! This class was difficult in the beginning because I hadn't taken calc in high school. The first half of the quarter feels like a review of high school calculus which is hard to keep up with if its entirely new to you. Homework is LIGHT but theres lots of practice available if you want it. Wu is really great about asking for feedback and actually taking it. if you have a problem and bring it up, he will definitely do his best to fix it. The second half of the quarter is much easier than the first half and the second midterm was much lighter as well. My TA was William Chang and he made the course a million times more understandable. I dont know if i would have gotten through the first half of the class without William's help. He posts answers to the homeworks with solution steps which are really helpful. He also hosts midterm reviews and made a discord where he answers questions. Wu also has a similar program where he answers individual questions (that can be posted anonymously) and theyre available for everyone to use. math 31a was rocky at the beginning as i think everyone was getting their footing with the course (wu, the TAs, the students...), but it is really ending on a high note. Not sure what the final will look like as its too early, but I'm confident that it will be fine.

Professor Wu is incredibly knowledgeable and formulaic, and he responds really well to feedback. You might have trouble if you've never taken any calculus, as he tends to cover material extremely quickly in lectures so you will probably have to do a bit out outside work, but the class is well structured and he takes test material from the homework sets and example lecture problems. If you want to do well, make sure you know how to do the homework as the vast majority of your grade is midterms and the final. I found the discussion sections rather useless unless you have some question you want to ask the TA, but really you can find the answer to most questions online. He doesn't make you buy any textbook which is nice and all his lecture notes are in one PDF which is helpful. I would take this class with Professor Wu again.

I feel like a lot of people are being dramatic in their reviews for this class. Math 31a with Wu wasn't that terrible and considering everything that was going on at the time (TA strike) I think he did the best he could. Sometimes he does overcomplicate certain topics, ( I think he did so with limits) but overall it was a pretty solid class. Also, he curved the first midterm so that if you got a certain number of points he would just give you 100% :)

I do not recommend, TBH I could have gotten a better grade in this class but it honestly was really difficult for me considering the lack of clarity and communication. The professor was really unorganized and instead of simply solving problems he wrote paragraphs of proofs complicating the most straightforward things and on the exams, each question had multiple parts AND he made you state the theorems. The worst factor that affected my grade the most is that for the 2nd midterm and final (bc the TA strike) instead of shortening the tests he made us do all 5 very long questions with many parts and chose two random ones to grade and we didn't know which ones. This class is not thattt bad but it was really hard to adjust to first semester of college. If it comes very easy to you you will be fine but if you didn't take calc in highschool please don't take this class.

The best thing about this class was definitely the recorded lectures. The class was at 9am so getting to class on time was kind of challenging but the professor recorded every single lecture and would upload the day of. The worst thing about this class was the professor's indecisiveness. He would change his mind every week and was unsure of many things. It is understandable since this was his first year but it made the class extra challenging for no reason. Personally, I had not taken Calc AB in high school and I was confused most of the time but Khan Academy was definitely a very useful tool. His office hours were definitely useful in terms of explaining the homework however the room was very very small and the students would have to sit outside the room to be able to at least listen to what the professor is saying. The tests were manageable since he used most of the materials from the homework and the practice problems however he expected us to be able to finish them in 50 minutes even though each problem had over 4 parts. Overall, the professor was definitely unlucky since it was his first time teaching and because of the TA strike but he could have managed the class better. I do not suggest him to someone who has not taken calc AB before.
