Sat Retake??-Help Please!

<p>I was waitlisted for fall but I definitely want to get in. I was thinking about taking the SAT this saturday, via standby, I would be able to send my scores by May 27thish.. Ums waitlist doesn't close till Mid June, so i figured I could send these new scores before theyre done with the waitlist. this is of course assuming I do better. Does this sound like a good idea? Would another 40 points maybe between CR and Math help my chances? Advice appreciated!</p>
