Retaking SAT?

<p>Hello
At the moment, I am a senior applying to Cornell, UVA and Virginia Tech.
I was wondering whether I should retake the SAT on January, as these schools seem to take those SAT scores.
However I worry that I might score less in the SAT (plus I have a lot of tests around Jan) and they might take that in consideration.</p>

<p>My current score breakdown is
CR: 730
Math: 700
Writing: 660</p>

<p>I definitely need to improve my Writing and Math, but I worry that I might do worse in my critical reading. I know that these colleges superscore but do they also see the other scores? (esp. since Cornell asked for all my scores, and my first one was quite weak - CR 590, Math 640 and Writing 650)</p>

<p>Thanks</p>
