Good vibes...point blank.
You could go to the most prestigious, highly rated, yada yada yada...college in the nation and still be completely miserable. If you don't feel comfortable, don't like the campus, and aren't happy with the student body...well, then was it really worth it?
In my opinion, I'd rather go to a lesser-known, less prestigious school that I feel comfortable at and *LOVE*. But hey, that's just me.
Really, some of you on here worry WAY too much about a school's name than what's really your right fit.
