I want to get at least eight hours of sleep every night (go to bed at ten and wake up at six). I mean, I'm fine with getting six and a half or seven. I just don't want to be up at 12:30 doing homework every night. I just don't want to be a walking zombie.

Any advice from current juniors, seniors, teachers, school counselors, and high school graduates would be much appreciated!
