Presents concepts well, is able to answer questions. HW, quizzes, and tests are straightforward. A bit awkward and lectures can be slow - I felt some topics could've been covered more in-depth, but Slava's a good guy. Also, read the textbook - complex is a very rich subject.

Krushkal is a nice guy and not a bad professor. Unfortunately, he's not a great one either and this material is fairly difficult. However, it is not necessary to have taken a proof based class for 3340, which is a plus for some.
