A question for the Americans on my flist

[gothikmaus]

Dear American people, I have a question about university/college. Yes, it's for a fic. When a university accepts you, do you need to go in for an interview as well? Would it make sense for a student in 11th grade to use spring break to have a look at different colleges? Or is that something you usually do after you've been accepted, so in 12th grade? Or you don't do it at all?

Sorry for the stupid question, but the university system is completely different here and I really have no clue.

Thanks!
