Confused about retakes

<p>I have a 33 ACT composite:
35-english
35-math
32-reading
29-science
8-essay</p>

<p>I have only taken the test once. I have 3 SAT subject tests--740, 760, and 790--and I'm not sure if I should retake the ACT. My problem is that I took the ACT for the first time in April and I exhausted all of the ACT tests. I would like to take it again since I only took it once to see if I can go up, esp. since my essay is sub-par, but I don't know what to do to prepare. I would be taking it, of course, next fall, so would I even remember stuff? Has anyone been in a similar situation? </p>

<p>Help please, thanks.</p>

<p>Side note--applying to ivies, top schools, etc.</p>
