I'm taking them on Sunday at 8 AM (EST). I'm taking the Biology E/M test, and not doing that great on practice tests. On my last diagnostic test of 95 questions, I scored a 600 out of a possible 800. Anyone who's taken them have any tips for me? General tips on SAT/SAT II exams are nice, Biology test tips are better.

For those who don't know what these are, they are big exams (typically 80 multiple choice questions) on various subjects (including Biology, Math, etc.), which colleges/universities look at to influence their decisions on accepting you or not. So if anyone has taken similar tests, any advice would be appreciated.

You (and I) have until Sunday, June 2, 7:30 AM (EST, I'm in NJ) to help me out...hope you can.
