SAT v. ACT scores

<p>I got a 2020 on the SAT
R: 680
W: 800, 11 on essay
M: 540 (really funny after an 800, I know)</p>

<p>...And a 31 on the ACT
R: 34
W: 35, and my combined score for English/Writing is 32, since I got an 8 on the essay
M: 27
S: 27</p>

<p>My question: Should I retake the ACT to improve my combined English/Writing score, or the SAT to improve my math score? I LOVED the essay on the SAT and the Math/Science on the ACT. I don't know which to retake, or if I should retake at all. I'm a pretty smart person and am going to apply to competitive schools in the future.</p>
