Ivy League Hopeful ACT/SAT Subject Test Dilemma

<p>I just got my SAT Subject Test scores back and they weren't what I was hoping for:
690 USH and 630 Spanish.</p>

<p>For most schools (ivies) it says that you only need 2 subject tests OR the ACT plus writing which I already took. I got a 31. </p>

<p>From the Results threads I've seen, hardly anyone has gotten in without subject tests. Mine are lacking however and I have a decent ACT plus writing. </p>

<p>What should I do in regard to sending the subject tests or not?</p>
