Since you have studied and prepared, you've really done all that you can do.
Now comes the part where you RELAX. There's really nothing else to do. Listen to some of your favorite music, watch a movie, play games on the computer - the key is to relax. That and get a good night's sleep.
Tomorrow, listen to your MP3 player for as long as you can - then just take the test.
I know that sounds really simple, but it is really that simple - your biggest job now is to relax.
