Don't think that way. Don't go into it expecting to fail..then you will. That the way I thought back in school. Go into take the exam with a positive attitude. Tell yourself "I can do this." "I'm going to pass!" Stuff like that. Just do your best, and I'm sure you will pass (:

Cutting.. That's not a good coping method.. I used to, then I was sent to a Mental Hospital for it.. I learned that there are several better ways to cope. Whenever I'm feeling down, I either listen to music, play a game, or do something creative. Like now, I'm carving a set of wooden knuckles.. Go for a walk, if that's what you like. Just figure out what helps you focus and calms you down that doesn't involve harming yourself.
