2. Get someone to do a final proofread for everything. Even those stupid little short answers. You just might have missed a typo. I did. x_X

4. Relax. I know it can be hard at times, but you're only going to do yourself more harm than good. Find an activity you can commit yourself to if you don't have one like dance or singing or shooting freethrows. Make that time your time to unwind and restore yourself for the work ahead.
5. You'll get into college. And i know you've probably heard this before, but whatever. It doesn't matter where you go; it's what you do with it. Honesty lies in the cliches, folks.
