Subject Test scores in...what are my chances?

<p>My subject test scores just came in and they weren't that great.</p>

<p>Lit - 670
Math I - 720
Math II - 760</p>

<p>Total - 2150</p>

<p>Does this badly screw my chances at Harvard/Brown? How important is the SAT II score?
And should I retake?</p>
