Are guys nicer in college?

Or are most of them still immature jerks. Keep in mind I said most, I'm not accusing all of you of being bad! I'm just wondering because I'm starting college this fall. I know it depends on the guy, but in general, what would you say?

I do not mean to insult anyone! I understand girls can be just as bad as guys. I'm not in any way claiming that we are better, please don't think that. I just want to know around what age most guys tend to not care about things like popularity and stuff, when they move on from the whole high school/teenager mindset thing.
