SAT II Help

<p>I recently took the SAT Subject Tests:</p>

<p>Math II: 710
Bio M: 750
Lit: 610 </p>

<p>I really didn't have time to practice for these and I never took the literature course before taking the test so that's why I have such a low grade on that. Im thinking of retaking math and lit in october because I really want to go to an ivy league or other top school (maybe NYU stern). Do you think I should retake them? And if I do I still might have to send both scores to some colleges like (yale)- will that 610 dramatically affect my chances (I have a 34 ACT, E:35 R:32 M:34 S:35) .
I don't really know how these SAT IIs work, so thank you for your help!!</p>
