I always thought 8AM classes were one of the best innovations I ever did. I had a double-major, did all the athletic bands, and I was a commuter from ~30 minutes away (haha free room and board no debt d00ds!
DD), and then TA'd and RA'd later in my undergraduate career and through a quickie master's, so coming early in the morning (a) forced me to go to bed at reasonable hours and (b) well, big, open times in the middle of the day between 9AM and marching band at 4PM/basketball games at 7PM... might as well get some work done... I know the pressures must be different when you have your own living space where you can safety/comfortably take off clothing and lay down to rest, but I never had that, so it forced me into a workaholic mode, which led to some good grades, lots done, learned a lot, all of which paid off with a real job.
