I'm 23 and due to financial reasons, I'm going to a 4 year university for the first time in August. Has anyone else gone this "late" in the game and what was it like?

I did do some community college so I'll be transferring in as a junior. I will be living in a dorm on campus as well. I feel a bit "old" to being living on campus but what the hell. So, has anyone else had an experience like this?
