I know this might have been already asked ad infinitium, but I thought I would pose a different kind of question: How much did you guys improve from your 1st disgnostic test to the real thing? What do you think is an average increase in each section? Just so you know, I just took TPR diagnostic 481 and made: 9V, 6BS, and 4PS. I know how crappy these sciences are, but I'm hoping that actually studying before the test might help! P.S. I loathe G. Chem and Physics. Thanks!
