In high school I went to bed progressively from ~10 freshman year to ~11-11:30 senior year. College I try by midnight, but I fail at that usually.
Rant: so freaking busy rarwarararararawrarwarawrarwarawr. And english in college is so terribly a waste of time; well, actually, if I was in high school it would be good. But I just want to go to my courses to be straightforward--math, fyzix, a circuits course, etc. They have set schedules, set problems for homework (not collected though), and I can be quizzed/whatever and see what I do wrong.
English there are things like "class participation" and silly little side things I don't want to spend my time on at all. Not for anything that would be graded anyways.
