Do your homework. If you have homework due on Monday that was assigned on Friday, don't start the assignment at 11 p.m. on Saturday. Take your homework seriously and try hard problems, even if you're not sure on them. If you are really having trouble, ask a friend or a parent. Don't stress about your homework though. Don't let yourself go over 40 minutes a night per assignment, don't procrastinate either. Manage your time.
