I would not recommend taking this class. Professor said 70% average on midterm was good enough because it's passing. Poor lecturer. Prof. said that she'll make practice final easy but the actual final hard, like what? I got every solution on a midterm correct, but got an 85% because I didn't show "enough work" on the simplest problem and questions expected solutions in different forms that weren't explicitly stated.

Math 32b is notoriously the hardest math lower division, and taking the class with Wern made that experience an utmost reality.

Wern is an extremely kind and gentle person. Yes, it's Wern's first year teaching here, but honestly, the entire scheme of the class was so absurd. Lectures were taught from the textbook, but the explanations seemed so unabsorbable! Reading the textbook helped me a lot with Midterm 2, but for me, Midterm 1 and FINAL were just NOT it.

I cannot forget to mention that there is basically zero partial credit for the exam questions; it is insane. I spent a good while chatting back and forth with a TA to justify some partial points, but still nothing. For those who are genuinely great at math, you'll do well in this class, but overall, it was not a pleasant experience for me. I am no genius, but I do put in effort to learn; this section didn't make it any easier.

DO NOT TAKE THIS CLASS.

I gave up going to lectures Week 2, and I am glad I saved three hours a week. There is no reason to attend class unless you want the book to be read out to you but made more confusing. The problem sets are somewhat manageable, but way longer than other classes I have taken. The first midterm and the final was abnormally difficult. I was told the final was intentionally made more difficult because the second midterm had a high average. The final was an absolute shitshow where I spent equal time solving the questions (or rather scratching and redoing the work) and staring into my friends' faces with an equally reciprocated sense of dread, disbelief and WTFness. If you don't care about your GPA or actually learning, then take this class, otherwise run.

Trust me and avoid this class. It's for your own good. Yeong manages to make the textbook's concepts seem more complicated than they already are and just doesn't want the class to get a good average. She literally made sure to make the final harder because she found the class average for midterm 2 to be too high (it was in the 80s) and whenever asked a clarification question during a lecture she wouldn't know how to answer and would make presume to make us more confused. The homework assignments are literally graded so harshly for no reason and the midterms are unnecessarily hard. I would never recommend this class to anyone.

the final is CRAZY
no recordings, notes and PPT
not recommend if you have a better choice

Confusing lectures, hard tests. 0/10. She literally said "The average was too high (literally an 84) so I'll be making the final harder so the class average is lower"?? The final was HARD btw. Super unclear lectures, really boring. Take it with someone else if you can.

I think Professor Yeong has gotten much better since last Fall. Her grading was fair and although she mostly just teaches straight from the textbook, the homework and worksheets she provides helps a lot with studying for tests. Lowkey the first midterm was kinda hard. The content wasn't bad but there were 8 questions for only 50 minutes (however they were pretty lenient with partial credit). Second midterm wasn't bad at all and neither was the final. You might need to teach some of the content to yourself because she's not always the best lecturer but it was manageable. Overall would recommend this class with her.

If I wanted to have the textbook and its examples read out to me, I would have used the audiobook function on the textbook. Class sucks, this professor is worse. If you think you can learn the content without lectures, go ahead, tests are not tricky. Id avoid though.

Wern is getting way over-hated here. She is a super nice woman and I think her lecturing has improved a ton since she started and I'm sure she will continue to get better. She helped me in my hour of need when everyone else abandoned me. I love Wern.

This class is definitely the hardest math class I've taken thus far. That has less to do with the Professor Yeong and more to do with the subject itself, so be fair in your expectations for how easy this class is. Professor Yeong is an average lecturer but her office hours are very helpful, so please attend those often. There are two midterms and one final. The first midterm was incredibly hard to me but the second one was very manageable. The final was cumulative and quite fair. Each homework assignment consists of 10 questions and there are around 8 assignments in the quarter. Regarding the first few weeks of class, make sure to learn triple integrals in spherical, cylindrical, and cartesian coordinates as well as possible. It takes a lot of practice and not knowing them well will make the first midterm much harder.
