In Russia, do you stay together with your class all throughout high school? That is, did you share a core set of classes with a set of about 25 people for four years, with only certain elective classes where you would be split up (like music or art)? If you do, I think that's the difference. Here in America, depending on the size of the school, every year there is no core group you share most classes with. You sign up for classes, and sometimes friends choose to stay together, but otherwise most classes come with a set of people that is likely to be selected from the whole grade. There are academic tracks for high/medium/low achievement in Math, English, Science, etc., but even in medium-sized schools you could have a class with a significant percentage of the students in the school every year. Some schools are quite large. I went to high school in both Croatia and America, Croatia having fixed classes where students stayed with their cohort year after year, and I was surprised how different the social environment felt. Even for the more socially awkward people, people weren't really rejected or bullied-- because you would have to see that person for the next N years of your life. Whereas in America, "fuck that guy, I only had a health class with him once, his voice is annoying."
