I took the SAT 2s in May and got 740 history, 740 chem, and 690 Math II. I signed up for all three again in June before I knew my scores. Now I know I can get the MAth up (have been studying) and I know I can get my History up, but I am not sure about chem. Currently I am looking at top tier schools such as Ivy and MIT(I really want to got here). Should I try the chem again, or is a 740 good enough. Basically I 'm asking if I should spend the next week reviewing it or spend more time ensuring I get a higher Math II score. Thanks for any feedback in advance.
