Tufts dilema

<p>I really love tufts and it is my top choice. My problem is that my SAT scores are not good enough. I am retaking the regular in December. My subject test scores are only in the 600s. Should I apply EDII January first, or take the subject tests again in January (they accept them) so I can boost my scores and apply regular decision? Which do you think would help my chances the most? </p>
