Would I fit in at Ole Miss? Students/Alumni ONLY. and Midway College question, Students/Alumni ONLY as well?

I went to Ole Miss. You will not get shunned for not rushing. Become friends with sorority girls or date a frat guy and you will get into all the greek parties, anyway. Honestly, almost ANY girl can get into a frat party at Ole Miss. If that is not your scene, there are plenty of people not in the greek system that will have fun parties. More importantly, Ole Miss is a beautiful campus and you will enjoy your time in Oxford (even if it is only a year).
