Beagle,
Take a deep breath. the one online is very hard, and is the same as either the "free" practice test or the diagnostic one they give in the class. Add at least 3 points to your score. kaplan is notorious for making the first couple of tests harder than the real thing. That is one bad thing about Kaplan, their scores give a misrepresentation of what you will get. Most likely, you will do much better than that. Unless you guessed and got lucky and never reviewed all the answers.
A week before the test, I would just review everything over and over again. marking off everything you know and stuff you know you will forget. and then the night before, relax and focus on the stuff you might forget (formulas, theories, mnemonics (King Philip Came Over For Good Sex = kingdom, phylum, Class, Order, F??,Genus, Species)
Crap like that, you know what i mean.
You will do good, think +++.

P.S.:How did you do though, in general. Feel free to PM me or write on this thread. I can let you know how I did also when i get home, but i don't have the scores on me though.
