I know this is going to be hard to do, but just relax. What I did before my test was nothing out of my usual routine. I studied my usual # of hours, ate at usualy times. Go to bed a little early, b/c you might not fall asleep instantly. Eat a normal breakfest. Basicaly, just be yourself, and be confident that you know your material. Don't be intimidated by others posting about bad test conditions and so forth. If you have done enough studying to this point, you won't have to cram, and will do well. Good luck.
