goodluck if you have him

The professor has been audited three times. They use a Chinese textbook, but does not explain anything in the given English textbook. They are incredibly rude and when a student asked a question in class about a topic, they responded later in an email to everyone, saying "Why would anyone think [that]". Avoid at all costs. Atrocious.

Professor makes a bad first impression, was tempted to drop on first day. But, his accent is only a problem the first day, and he teaches things very clearly. You can choose to have homework included if it benefits your grade. Very comforting environment, ended up really enjoying the class and it really changed the way I think.

Lectures/content from Yang are very disconnected from the rest of the Math 4B lectures. He focuses on proving solution methods for differential equations rather than teaching about their applications. He never posts anything online aside from homework assignments and some announcements, so don't expect any public lesson plans. Do not take.

I honestly should've switched out of his course after reading the reviews. He does not have structure in his class. He also doesn't have anything on the canvas page only the syllabus which doesn't seem to say much. I didn't know what was expected and honestly, learned more from the TA than him.

math department lock in
