The lectures were confusing and made very little sense. He focused a ton on proofs and theory that never came up on exams (as the exams were purely computational). The material itself is relatively easy, but it could have been explained in a much better way. However, the textbook does a great job at explaining so you can get by just teaching yourself. Also, discussion sections are a must- that's when the TAs go over a bunch of practice problems and explain the material in a much more clear way. Dr. Fan definitely made up for his teaching though with how easy his tests were. He gives you every type of problem that will be on the test, and releases past midterms and finals as practice. They're very straightforward, so if you can do the homework, you can do the tests no problem. Also, Dr. Fan tries his best to be helpful during office hours. He definitely cares and makes an effort for his students if you reach out to him.

If you're the type of person that doesn't really pay attention anyway this guy is great. The homework is always useful/super relevant for the tests and reasonable. If you're looking for a professor that clearly explains the subject, find someone else. He's definitely a nice guy and is super smart but for me (and everyone else I know in the class), the textbook is much easier to learn from. But at the end of the day the tests are super reasonable and he doesn't try to trick you so I'd definitely recommend taking him if you're okay with terrible lectures.

Fan always posts his notes on CCLE. His notes are very organized and handwriting is clean. Workload is a little bit heavy but okay. Easy exams. Xuan ta, xuan ta, xuan ta!!!

It's a pretty easy class. I barely read the textbook but followed all the lectures. Sit in the front rows if you could. All the exams are easy. Highly recommend him.

His lectures are terrible (half of the time he was just mumbling to himself, and aside from that the class was cramped and if you couldn't get a front row seat you couldn't see shit), but the midterms were dead easy (the median on the second midterm was a 98%) and the final wasn't bad either. I mostly relied on the textbook and my TA, because the lectures were impossible to follow. I wouldn't recommend taking him if you have a choice, but if you do take him, learn from the textbook and you'll do fine.

Fan was a good guy and gave easy homework and fairs exams. He even told the class every type of problem that would be on the final.
