I have a 760 in Chemistry, 710 in US, 700 in World, and a 690 in Math II.
What colleges are you applying to? For what majors or intended majors?
For Biochem or something along those lines at UCSD, Emory, NYU, Boston College/U, Hopkins, Pitzer, UMich, and USC.
Each school will have differeent requirements - 1 Subject test or 2; one math and one science, or specific subjects.
From my experience your Chem score looks great but your Math 2 score looks a little low for competative science programs (I believe the conventional advice on Math 2 is anything over 700 is ok.)
