Reviews of professor Ivan Korolev

Rating: 3.0/5, difficulty: 5.0/5
Incredibly hard class and a lot of R coding. Took some time to get used to because of a speaking issue. Helpful office hours.

This class was incredibly hard, but he really does care about his students, even if it is not obvious at first. If you go to him outside of class he will help you. Take advantage of that! Also, this class requires a lot of R coding. Good luck if you take the class with him.

Took online during pandamic, extremely useful. I was interviewed for jobs later in senior year and thanks to the class I was actually able to prepare them well. I had a medical emegency and text two hours before final midnight and asked for an extension, and he's cool about it. Smart, if you talk to him and actually try to learn R you will benefit.
