I had him for 115A in fall 18 and 170B in winter 19. One warning: he goes VERY fast. He barely gives you enough time to write notes, then expects you to have digested it quickly enough to ask thoughtful questions (which almost no one has). One time he got mad because he said the notes are online and we should be paying more attention in the moment instead of writing. He wants to be engaged but may get lowkey irritated if you ask a dumb question.

He definitely has an accent (Belarus) , but after a couple weeks you can get past it and understand him pretty well.

His homeworks are usually due on fridays, and the homeworks are generally difficult, so make sure to put some time in. He likes to include bonus extra credit hw problems. The midterms are toughish but not as tough as the weekly lecture and homework (he's a somewhat generous grader actually). Cheat sheet allowed.

One thing for sure though, is that i feel like i learn a LOT more in his classes than i do with the other adjunct professors ive had so far. He really makes sure that you understand the subject. And despite his intimidating eastern european energy, he really does want to help you and he is very nice (but blunt) in office hours. For that reason, I would take him again.
