<p>Colleges don’t have a preference. It is ok to submit only the ACT (depending on the school’s policy). Some schools require you to send all your scores, some do not. </p>
<p>By the way, you got a 35 on that practice test – you average the 4 scores. 35 is much better. You could just equate it to the SAT through sources online – 35 equates to about a 2320.</p>
<p>Take the test you are more comfortable with (obviously it is the ACT for you). The best prep book is The Real ACT Book (red book). If you want to prepare for the SAT, get the Collegeboard Blue Book</p>
