Ha GRE's are sucking the life out of you? Wait till you actually get to grad school, it gets worse before it gets better. I strongly agree with the people that have told you to take tons of practices tests and sleep well the night before. My two other pieces of advice are do not do not get nervous, just relax, nothing but bad can come from getting stressed so don't. And to go along with that advice, if you can swing it (depends on how prepped you are right now) take the day before the test off. Play nintendo, frisbee golf, anything but the GRE (just nothing that gets you hung over). Good luck, you will do great.
