I know more than a few students attending top rated public universities.
According to one survey conducted by the National Survey of Student Engagement, most college students spend an average of 10–13 hours/week studying, or less than 2 hours/day and less than half of what is expected. Only about 11% of students spend more than 25 hours/week on schoolwork. [1]
a "Full time" course load is 15 credit hours, which is about 5 classes.. a student taking five 3-credit classes spends 15 hours each week in class..
In the past I have run college level internship programs, both for credit, and critically for this discussion not for credit (meaning no affiliation with the schools). I have had no problems scheduling students work around their course schedule, for which they normally have 2 or 3 open days for work.

That school definitely is not in danger of losing its accreditation any time soon. It also didn't have any frats/sororities, and there weren't any bars within a 15 minute drive.
How do you not see that manifest in reality? What school doesn’t have classes 5 days a week that people are taking, or otherwise expected to be somehow participating in an activity related to education? Sounds like a school that should lose its accreditation.
