I once tried to take Quantum Mechanics at 8am. I went for a few weeks, and then I started falling asleep in in class. One day I realized before getting out of bed that I just fall asleep there, so I may as well stay in bed, and it was all over... ...so I tried again next quarter. This time, it was Quantum Mechanics A--I had previously tried skipping into C--so the professor probably just thought I couldn't handle the material without the stuff that came in A/B, and realized I was in "the wrong one". Well, it happened again. I tried a third time. This time, showing up to B, the professor must have figured out what was happening and I kind of remember her laughing at me a bit. When it happened a third time I gave up, stopped ever trying to do early classes, and, 20+ years later, give students the advice you were given ;P.
