I think I have already written about this, but I don't remember in which of my threads so I will say it again. You have lectures where there are 50-600 people (well, 600 is in first year, now it will be up to 300, still very anonymous). Then, you sign up for your seminars and in my case, there are completely different people on each of them. The educational system used is strictly anonymous. To wrap it up, I know to people on my faculty because they were my classmates during high school. One of them dislikes me and the other one can be nice, but also tends to be offensive towards me.
So far, I tried talking to my classmates, but they don't seem to want to find friends. Most of the time, I didn't even got to know their names
