<p>Do u just need the ACT for Ivy League? I<code>m taking the SAT and ACT, but i</code>ve the feeling that my ACT would be better. Should I just send my ACT if I screw up my SAT?</p>
<p>some schools require SAT subject tests even if you take the ACT, like Columbia. However, I do know that Yale only requires no subject tests if you take the ACT. You should send whichever score is better, but if you have to send subject tests, then colleges will see your SAT scores as well.</p>
