I feel like you either love him or hate him and there's no in between. I personally didn't have a pleasant experience in his class because it lacked structure and lectures were very hard to follow, plus his handwriting is impossible to read. The exams are hard to prepare for because he doesn't give you any practice material beforehand. Self study.

Very hard to understand and his handwriting is pretty much illegible. Lectures are not productive at all. Overall there's very little organization to the class and exams are difficult to prepare for since he doesn't give you any practice problems. If you have him you just have to self study and assume everything is gonna be on the test

What everyone else said is true. Don't fall for it.

The professor doesn't provide practice exams, which makes it extremely difficult to prepare for tests. TA rarely replies to emails, and the professor's handwriting is hard to read. Lectures are boring, and 70% of the homework questions are hidden in chaotic lecture notes, making it a challenge to even identify each word. It was a tough experience.

I can see that this one student keeps writing terrible reviews repeatedly. Pro. Cho was the best math professor I have ever had in my life.

do not take with this prof, worst prof i ever have encountered so far.
