Reviews of professor Yu-Shen Lin

Rating: 3.0/5, difficulty: 3.0/5
The lectures are fast and sometimes hard to follow, but Lin posts lecture notes which is helpful. The exams problems are either straight from the lectures or are similar and we only get 45 minutes for four problems. There are no practice exams, but if you know everything on the lecture notes, you should be fine. Be careful of the final exam.

Best math professor at BU! His tests were super straightforward and he doesn't try to trick you, and he's super nice. Easiest A of my life lol
