<p>I disagree with PrincetonPreppy, your SAT scores are irrelevant. Since your ACT scores are outstanding and you only need to send EITHER SAT or ACT, I wouldn’t waste any more time on the SAT. Having said that, your grades are low - probably not what Princeton is looking for unless as a track guy you are running sub 1:50 in the 800. Still, it’s never too late to improve your grades. You have to look beyond the undergraduate years to where you ultimately want to be and chart that course.</p>
