<p>I agree with the previous poster – consider retaking the test. I hadn’t taken any math classes since freshman year of college and recently scored an 800 Q. You could easily match that score. One thing you may want to consider is not studying at all the day before the test and just let your brain relax. It seems like you gradually intensified your efforts studying for the test until the test day – it’s usually preferable to the opposite. That is, study hard until a week or two before the test, then gradually lessen your efforts each day.</p>
