Yakov Yasha Berchenko-Kogan

Yasha is very smart but a god-awful lecturer. He goes way too fast and covers only super simple examples in class. Going to lecture does not prepare you at all to do the homework sets. In class, when his style of lecture was criticized, he blamed the students for not reading the textbook. I would avoid him at all costs.

Yasha is definitely a math genius, but that means that he goes way too fast in class and assumes that his students have background knowledge that they don't have. The way he explains things makes no sense: I've never been so confused for so long in a class before. I had to switch professors so that I wouldn't fail out of calc II.

Assigned a ton of homework, the most of any of my classes. He's a math genius but that just makes him awful at explaining concepts in class. Exams were really hard and got more difficult as the year went along. Not much sympathy for his students either.

Not good. Hard to follow in class, and assumed we knew things that we didn't know. Homework was absurdly long. Spent so long trying to complete the homework that my studying for the tests was cut short, and so I did not do as well. Diffeq is hard enough with a good professor - Yasha just made it harder.

Took DiffEq with Yasha this past semester, exams were mainly based on practice exams but the last two were way more difficult than the first two. Gives WAY too much homework (both written and WebWork), homework sometimes took 12-15 hours to complete every week. Office hours very helpful
