Well, I'm a Beta pledge at Nebraska, and we have a philanthropy called the Beta Buddy program. It's sounds kinda like what youre involved in, although I don't think its neccesarily about what college is like. It's more about helping underprivilaged kids a role model, and helping them. Of course I'm only a pledge and haven't even started yet, so I may be wrong, although I was in a similar program in HS. I may be able to give you some ideas from that, let me know what you have in mind.
