Pretty good question.

I remember two things about my university.

First, I was a 'provisional' admission. Which meant that I had to maintain at least a C Average for the first year, Had to log a certain number of hours in one of the 'study centers' every week (Although I could technically do whatever, so I wound up reading a lot of books once I had my coursework done,) and there was a 1 hour a week pass/fail that was primarily following up on the study center logs and connecting students with extra help if the needed it.

Second, I remember a -lot- of people pledging a fraternity their first semester, and statistically it seemed to cause a much higher fail rate... In fact, I tried pledging a social fraternity my second year, dropped out in less than a week because I realized the time commitments and requirements would have tanked my grades; sure enough out of the entire group that didn't drop out, less than 10% survived through the full year.

That second point actually got so bad that, for my last year they actually banned Social fraternities from recruiting first semester freshmen... not sure whether it stuck or not after I graduated tho.
