In a top Russian university you simply would not have the time, and they would not hesitate to kick you out; graduating from university can be more difficult than getting into one.

Are you sure? I studied math in MSU in early 00's. Most of my coursemates drank a lot. I took some silly pride in drinking a lot and still learning enough to get good grades, but a lot of us just weren't bothered by getting worse grades. You had to be exceptionally and repeatedly bad at the exams to be kicked out.
