It was painfully obvious that nearly nobody wanted to take 8:00 AM classes when I was in college. There were two friends of mine who took the same 8:00 AM math class one semester, and they never met in lecture, except on quiz days.
Even the early birds I knew didn't quite like the morning classes, because they then had to rush towards lecture halls first thing in the morning, rather than strolling leisurely to the library, eating breakfast, or jogging and taking a shower, which I suspect is what many early birds most enjoy about being an early bird.
The problem is that there are seminars and stuff that occur at at like 7 or 8 pm, so university life almost necessarily extends late (after lecture, dinner, assignments, projects) in the evening at least on some days. This is further exacerbated by the fact that given how many group assignments there are, individual student rarely have total control over their own schedule. Even if you carefully choose your classes, avoid all late-night sessions, don't party, plan your life, it's still incredibly hard to sleep before 11pm consistently.
