<p>Hi I am taking both of these tests in June, I havent started studying for them yet. I just finished with finals and AP tests, and I am going to start studying soon. I took the barrons diagnostic for Math II and got 45/50 (none omitted). I havent done anything for SAT chemistry, but I scored 80~85% raw for AP chemistry MCs. Do you think I can still get like 750+'s if I start studying soon, how generous are the curves?</p>
