Dartmouth, Swarthmore, NYU requirements question...

<p>So, I'm applying to those schools. I'm borderline sure they need the SAT II's if you took the SAT I.. However, I took the ACT (31)... Do I even need the SAT II's or not? I took a USH practice test and only got a 600.. That's not even ballpark for my schools.. What should I do? Also, if I signed up and just don't show up, what happens?</p>

<p>Seriously people, I need help! x(</p>
