Nice guy, doesn't take himself too seriously, and his accent is not too hard to understand. Lectures were pretty clear but I found taking my own notes on the textbook more helpful than going to them.

He does proofs in class, but the tests aren't proof-based. The final exam is worth 40%. Exam grading is very clear. You quickly get used to his Russian accent.
