Mizzou seems to have a pretty strong greek system. About 25% of our undergrad population of around 25,000 people are Greek. We have 14 sororities, 25 or so fraternities, and to be totally honest I am not sure how many NPHC groups.
For the most part you either love greek life here or dislike it, at least that the way it seems to me. AXJules can probably explain it better than I can.
