ACT and SAT or just ACT?

<p>Hey,
I've done the SAT thrice and super-scored a 2160 (760 math 690 crit 710 writing) with a 2100 single top score. :/</p>

<p>However, this october I did the ACT for the first time after being put down by my October SAT 2070 :/ and thank God I ended up with a 34 composite ACT (35 math, 35 science, 33 reading, 32 English, 10 essay)</p>

<p>Now I am in a quandary, as for the regular decision round I hope to apply to some top (CMU, UCs, Duke, Gtech etc.) for engineering but don't know whether I should send both the scores to the unis or just the ACT. Would I be at a disadvantage of any kind if I just sent the ACT without any SAT scores whatsoever? Or should I just send both?</p>

<p>Thanks :)!
P.S I am an international Indian student in Dubai.</p>

<p>No brain er — just ACT</p>
