When I got into university I found every course very easy, didn't attend any lectures, got all my workshops to run on the same day to reduce my face time and maxed out my free time to do whatever I wanted (work/friends/extra/etc). I'm a STEM major at a top 30 world ranked engineering school with good grades.
I've often asked if I could max out my classes and finish a degree within a year and a half - but I've never been allowed to skip more than a few subjects (tests/bugging the heads of departments).
University shouldn't be time capped or subject load restricted - people should be allowed to do as many as they wish - or you'll find more and more moving towards MOOCs instead.
