Socially how different is college from high school or how similar?

Like what is it like. In my highschool there are no real cliques and people have their own groups but still almost everyone talks. Its an international school as well.

Depends on the college, how many students and how many are from far away. It’s hard to answer unless we know the specific college. No cliques? Your high school may be unique.

It depends a lot on the school. Some tiny ones are like High School Part II and some big state schools are like their own country.
