Earlier quoted context omitted.
I can't help but think that for every student more into drugs/sex/drinking/clubbing, there is a kid out there who was genuinely interested in studying from the top academics that probably didn't even bother applying because they thought they wouldn't be able to get in (or won't be able to afford it). I am also surprised that the culture you describe seems to be tolerated at best and even encouraged at worst. Sure, it…
I spent some time with students in Russia and they were even worse! Most of Europe is similar to an extent, but sure there are people who are obsessed with studying and learning, but there are a lot more who are keen to get away from their parents, spend money on beer and find girls/boys. Most Asian students I met who had come over to Europe were pretty serious. Anecdotally some friends from Wales who went on a study…
I suspect there is a big difference in Russia between top science universities and everywhere else. In my opinion, humanities education is of very poor quality in Russia so I could well imagine a party culture there. But the curriculum in top science programmes tends to be so intense and passing requirements strict enough that I doubt there is too much partying going on. However, a lot of the coursework I suspect is also still too outdated and often irrelevant.
There is also likely a big difference between students living at home and living in dorms. Who knows what happens in dorms, but the commuting students in my opinion don't tend to get too wild.
Finally, the social scene is just structured very differently. There are fewer elected subjects, and most of the social life happens during/between classes - the whole year just spends a lot of time with each other naturally and bonds over common struggles. There is a culture of trying to involve everyone in some sort of social life. You don't have to sign up for anything - it happens by default. Although I think international students would be treated differently and actually perhaps excluded. Instead of clubbing or going to bars, social drinking revolves more around drinking in someone's kitchen and engaging in pseudo-philosophical conversations.
Of course, my account is from a long time ago so things may be very different now.
