He is a very nice person, but the class is very disorganized. Probability is an incredible subject but Sonkin fails to make it interesting. Exams are worth 100% of your grade and they are not easy and didn't align with the material from class.

I don't understand what he's talking about most of the time because of his Russian accent. Also he is really bad at lecturing and answering questions. Yeah he cares about his students a lot but most people just gave up on this class at last due to how unclear he delivers the lecture.
