Advice for a college bound student?

The fact that you are worried shows that you will go farther. If your really care about college, which shows, you will graduate. Your gpa is pretty high and your sat score is not really that low. Just go to sleep, relax, and know that everything isn't riding on this one test. I'm sure you will do great. Now just lay in bed and try to go to sleep so that you are well rested for the test. (my sat prep tutor said a good relaxation technique is to clench up all your muscles one by one, from your eyes to your face to your arms & legs and then relax them one by one, it sounds weird but it really works!) envision yourself doing well. It'll happen, you really have a lot going for you!
