egh, holly, i feel your pain. i already took the SAT's, got a crap score in math (which brought my score waaaaaaaaaaaaaaay down), spent the last three months getting tutored in math, and i still dont' think i'm going to do very well.
however, the SAT's aren't the only thing that determine whether or not you get in. At all the college's i've visited, they all said that your SAT's weren't everything, they looked at the things that you've done, the person you are, etc. don't worry, i'm sure you'll do awesome
