<p>I don't need SAT IIs for any schools early, but eventually I'll need chem, math 2, and lit. I also want to take one more stab at the SAT I before I apply anywhere crazy. I want to apply to Columbia and most likely Brown and Princeton. Is there anyway I could be prepared for all three by October 10th? (regular registration closes today and I'd say I'm decently prepared for all three, probably 600 range right now.) I wanted to retake the SAT I in November but should I take the SAT IIs in November or am I allowed to take them in December for regular decision?</p>
