What should I retake?

<p>I am an international student from Europe and I need your advice. I want to apply to HYPM and the like, so I will need 3 SAT II's. Right now I have these stats:</p>

<p>SAT I: CR 670 W 740 M 790 (1460/2200)
SAT II: Math IIC 800 Physics 780 Literature 600</p>

<p>As you can see, both my Critical Reading and Literature scores are very low for Ivy League (I am applying for finaid, too). I haven't registered for the December SAT, but I want to try to take an exam as a standby test-taker.
So, what do you recommend me to retake? SAT I (I want to improve only the Critical Reading, satisfied with the rest) or Literature? I am expecting only slight improvements, if any, on both tests. My plan was to take the Lit test in December, and retake SAT I in January (however, this would be kind of late). Any suggestions, thougts? Thank you in advance!</p>

<p>My honest suggestion? Don't sweat it. If your other stats are good, these won't matter much. Don't go SAT crazy.</p>
