January Retake Math 2--HELP!

<p>Hey guys.<br>
I took the Math 2 test this October and only got a 750. I was aiming for the 770-800 range. I studied with Barron's and got low scores on those practice tests (but apparently all of those tests are crazy difficult and getting over 600 suggests you'll do well on the test). I also took a CB practice test and got 800. I'm not sure what happened to me on test day, but I know that I seriously need some advice for reviewing and calming my nerves. I'm taking the test at a school I'm totally unfamiliar with, which will probably make me more nervous. </p>

<p>If you have any advice at all, please post them!</p>
