Fall 2022 - Professor Tong is the worst math professor I have ever had. Never once have I struggled with a math class here before. I took the entire series Math 31A, 31B, 32A, 33A, and even Math 61 before this class and passed every single one with an A. I was very confident in my math abilities up until this point and everyone had told me that this class was by far the easiest in the series so I was not concerned when there was a new professor teaching it. Big mistake. Never take this class with Tong. Her lectures were not recorded and they were essentially fast audiobooks with her handwritten notes of the textbook. She spent too much time going over the parts of the chapter that weren’t important and then rushed the bits that were important for the homework. To add insult to the injury, everyone started getting sick around week 3 because of the frat flu and because lectures weren’t recorded it spread throughout the class and affected all of my other classes (since I got sick from this class during all the other midterms too). Just avoid her at all costs. She will make you question your math abilities. This class had absolutely no reason being this difficult.

Professor Visan tells you at the beginning of the year that her tests are just as difficult as her homeworks. Take this advice strongly and do your homeworks and you will do well in the class. I redid homework problems (including textbook problems) before each midterm and the final and got an A. Simple class.

I actually had Wang for MAE 182A. During lectures, he basically does proofs then a couple of practice problems. He doesn't use the book at all. MAKE SURE YOU COPY EVERYTHING DOWN. His techniques to solve differential equations are actually very good and are better written than the book. So copy everything down and use his techniques. His tests were really easy and the average was in the 90s. Just re-do the homework and do a couple of problems from the book.
