My .02 -
1. Get a good amount of rest tonight. Don't stay up late trying to cram for the test. You need to be well rested and on your "A" game tommorow.
2. Don't try to cram for the test tonight. If you don't know it by now, cramming will probably do more harm than good. If you do any studying, just take a couple practice tests on the sections you didn't do so well on.
3. Relax during the test. I studied hard for this test for a couple of months, and when the test came around, I blew through the sections with no time issues (and scored well if your wondering, 8/8/9/65). Hopefully for your sake, you've studied enough, and if you have, then you don't have much to worry about.
4. Don't spend too much time on one question. Skip it if you can't figure it out within 30 sec. Once you're through that section, go back to the questions you skipped (be sure to keep track of them on your scratch paper) and look at them again, if you still can't get it, look through the possible answers and try to work backwards or just pick the one that makes the most sense.
- Case and point, I had a question that asked me about calculating something like resistance or some physics force that I had no idea how to calculate. But, I conceptually realized that the force they were asking me to calculate would be zero and so I easily found the answer by looking through the available choices for the force = 0.
This is all advice you've probably heard before, but that's because it's important. Don't neglect these simple tips and definately don't overthink the test. Go out there, do your best and you'll be fine.
PM me if you have any other questions. Good luck.
