<p>You need around a 33 to be competitive. The highest 75% at everything "below" Yale on the rankings is a 33, and you can get away with about a 31 or so at Cornell maybe. But it is safer to be a tad higher. Even then, no score on the ACT is going to guarantee admission to an Ivy League school. You should just send it in if you want to apply and see what happens.</p>
