Should I take the SAT or SAT II?

<p>Right now, my SATs aren't too high and isn't very competitive for Northwestern. I'm taking the ACT in October and am expecting at least a 30. I have one subject test in U.S. History and scored a 690. The last time I can take the SATs for Northwestern Early Decision is Nov. 1. My question is, do you think I should take the SATs again, since I'm not positive that my ACT score will be high, or should I try to score high on two of the subject tests to possibly offset my low SAT/ACT score.</p>
