If I take the ACT+Writing, Do I have to still submit SAT II's for the Top Schools?

<p>I want to go to Carnegie Mellon, Cornell, etc
I have an average SAT (2100), but low SAT II's (730 Math 2, 690 US His, 690 Bio) and I have a good ACT(34 Composite 11 Essay).
So my question is can I just submit ACT with writing, and not submit sat II's?
Thanks in advance</p>
