<p>perpetualmotion, Congrats on getting a 33 on the ACT. This score places you at the 99th percentile nationwide. According to the College Board, the ACT middle 50% for first year students at H is 31-34. Given this, I would submit your ACT scores.</p>
<p>This thread is almost identical to this one: <a href="http://talk.collegeconfidential.com/harvard-university/441906-sat-vs-act.html%5B/url%5D">http://talk.collegeconfidential.com/harvard-university/441906-sat-vs-act.html</a> -- just with higher scores. While I agree that the science score is a little lacking, it is still the score with the toughest curve on the ACT according to their percentiles, and I think most people who've been in admissions for years know that the science part of the ACT is little more than a test of reading comprehension--not actual scientific knowledge. A 27 is still the 93th percentile (for that portion only, a 27 in anything else is <91), and the rest of the scores are extremely solid.</p>
<p>The ACT math score is (obviously) significantly better than the math score on the SAT, while the rest pretty much line up with your other SAT scores. I don't really see the science as that big a negative, while I see the math as a pretty big bonus (especially since the ACT has trig and the SAT doesn't). It's your call, but I'd probably submit it under the assumption the positives of a 36 math trump the negatives of a 27 science.</p>
