I'm an American student currently studying at an American college (Hamilton College.) I'm unhappy in my current situation and am considering transferring to university in the UK. I know that international students can apply through the UCAS system until June, but would applying in, say, late Feburary significantly decrease my probability of being accepted into a UK university? It seems that for the acceptance system in the the UK works in a way equivalent to "rolling admissions" in the US.
Also, I was wondering about differences in university social life between US and UK universities. My college is small and far away from any substantial city, and therefore our social life revolves around partying in people's dorm rooms and hardly ever leaving campus. Do UK students generally go out to clubs, etc. on weekends, or do they hang out in people's apartments, campus housing, etc.?
