<p>joyo – Unlike the SAT, with the ACT YOU get to decide which of your sittings to submit to colleges. So if you take it a third time (or a tenth time!) no college need ever know unless you say the word; you will be able to pick the score you like best – presumably your highest composite from a single sitting – and ask ACT to send only that score to colleges.</p>
<p>I think you’re saying you’ve already taken it three times. If so, it’s probably not worthwhile to take it again. Unless you have some concrete reason to believe you could improve your score now, the general rule is that, after three times, you’ve probably achieved your personal best.</p>
