what to do??

<p>i have 4 days left before june subject tests (including today)
Im taking physics and us history
and i have the Kaplan book for both of them (3 tests left for each) and the Real SAT II's (official tests... 1 each) and the Barrons for both of them (3 tests, phys; 7 i think US)
what should i do with my 4 days (as far as which tests to take, for each respective subject)
and should i read the kaplan or barrons for both of them or at this point should i just study my tests?
im aiming for 800 physics, 750 US History</p>
