<p>The difference between your test results isn’t huge (I calculate your ACT score as equivalent to a 1980) and, seeing that you performed so poorly on some other tests, submitting the SAT reasoning scores would demonstrate that your 30 on the ACT wasn’t a complete fluke - the two composite scores are within a normal range of one another. I would also definitely submit both if your strengths differed. My son’s SAT and ACT composite scores were very close, but his English/Reading scores were higher on the ACT, whereas his Math SAT was his strongest score. We felt that they revealed that he could do high level work in all areas. </p>
