UC Irvine or Cal Poly SLO for business?

UCI is a great school, my friend is a Crim Major there. I've been to the campus a few times and sat in on some of her lectures and I can tell you from personal experience that's it's very diverse. It really depends on what kind of college dynamic you want to experience as well. I suggest that you visit both campuses before you make your final choice, see at which campus you feel the most comfortable because from my personal experience at the end of the day that's what it really comes down to. If you feel out of place somewhere you are less likely to succeed.
