This was one of the hardest classes I have taken. I did not take AP Calc in high school and I think that was part of my downfall. The professor made the simplest things the most confusing and even those who I knew who did take AP Calc were struggling. The midterms and finals are all questions that were on the homework, which means for every single problem sheet you have to answer every single question without a real answer key. Jeremy Wu never gave an answer sheet to the entire homeworks, but William Chang was amazing and used his free-time to make his own answer sheet. Of course without a real answer sheet from the professor, the hardest questions from these sheets were always on the tests. The final was good because he allowed us a notebook paper sized cheat sheet, but of course he used the hardest questions from homeworks and lectures. The only thing that saved my grade was the fact that we were allowed to drop our lowest midterm which meant the final had to be graded at a higher weight. Make sure you actually go to lectures because its not the same as the recorded ones he posts, and make sure you review the lecture problem examples and do every single homework problem to be successful.

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.

I must note that, having never taken calculus before, this course proved to be quite challenging for me (leading me to frequent the math tutoring center). Hence, if you are not prepared to invest the necessary effort and time, I would not recommend this course.Jeremy started the quarter as a challenging professor, but after receiving feedback, he made significant improvements to his teaching style. I highly recommend attending all his office hours, where he drops hints about test content that won't be posted elsewhere. The weekly homework only includes two mandatory problems, with numerous optional ones available. I suggest doing the optional problems, as midterm and final questions are drawn from both homework and lecture notes. Fortunately, all lectures are recorded, which is a plus for an 8 am class. Having never taken calculus before, this course proved to be quite challenging for me, I had to attended almost every office hour and additional discussion sessions. Hence, if you are not prepared to invest the necessary effort and time, I would not recommend this course.

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.
