Is math II going to destroy my chances?

<p>I am a white female in a public school in CA. I'm a sophomore. I have a 4.0 UW GPA, a 4.8 Overall (highest possible at this point) and a 5.0 10th-12th grade GPA. I am also a cheerleader and a trapeze artist, just to keep it brief. Cheer is a giant time commitment. I'm shooting for Johns Hopkins, Brown, Dartmouth, Lehigh, Tufts, and various others. I take the most difficult honors and AP courses available at my school. My jr. year schedule includes H Physics, AP calc, AP chem, AP english 11, AP US history, French 3 and cheer.
I want to go into science/(biomedical) engineering. I'm just worried about my SAT II scores. I haven't taken my SAT Is yet, but here are my scores:
Bio M-780
Math II-700
I don't know how much better I can do in math II and this was my 2nd attempt. The test just gets me! I've improved since my initial 610 (which I am very ashamed of). I know math II is a really high scoring test for most people. Is it going to kill me to have a 700?</p>

<p>colleges are not too picky on these SAT II subject tests.
I'd say that they can only help you, not hurt you
you're fine. And especially since ur a cheerleader (something out of the box)
and in good academic shape, I'd say it is up to your essays to determine your acceptance.</p>

<p>thanks... I was freaking out. I was told I "didn't exist" without a 720.</p>

<p>From what I've heard, just get above a 650 and you'll do great. SAT IIs don't kill people.</p>
