Worth retaking SAT to transfer next year?

<p>I have 1600 on the SAT. I want to plan to transfer to UPenn as a sophomore if things don't work out, like a Plan B to be safe.</p>

<p>The first test I took, I scored a 1400, end of junior year. This might sound dumb, but half way through the test, I had to take a crap. If anyone knows the biology of the human body, which I do, there are two sphincters... Anyways... Yea.
Then the second time, I scored a 1600, janurary this year. I felt like I got everything right. Apparently not.</p>

<p>So my question is... Will I go up another 200+ points if I take it again? What if I study a little? I never preped for any of these tests. How can I score a definite 2000+?
I think I got:
590 M
520 W
510 CR</p>

<p>Um... I'm preetty sure I can score around 650+ M, but CR and W are my weaknesses. Any input?</p>

<p>Also, I've always wanted to prove myself worthy, that I can score high on the SAT. I know that the SAT is BS and that it doesn't show how smart someone really is, but.... Yea.</p>
