Advice for a 6/17 tester...

Who doesn't feel like they have everything they want to have memorized memorized? Thought I'd have more time to commit some things to memory (mainly orgo reactions and some p/s, mainly theories of personality). Looking through my Kaplan quicksheets and taking notes seems to be stressing me out more. Should I just chill out? For reference, 509 and 510 on AAMC I and II, respectively. Ideally, not looking for a score lower than either of those.
