<p>Serious answer: if you’ve only taken it once, I think I’d retake in your situation. You are interested in top 20 schools, and you are interested in a science-related major. That 750 Math Level II is good, but the curve on that test means that it’s not super-good.</p>
<p>At some of the most selective schools, a 700 math is about at the 25th percentile. I don’t think that’s the best place to be, if you think you can do better.</p>
