Did you retake it? It's killing me to miss Borat on opening night, but something's telling me I'm making a wise choice. 
Since you're a traditional HS student I'd advise you to take it and not screw around. You're 17, and by the time SATs are given out again you'll probably have little time to apply to a college.
I didn't have this problem because I had around 90 college credits before I applied to any university. I was able to transfer as a junior, saving my parents a lot of money and myself a lot of time. I could have got a 9 on the ACT and still got in lol. Only thing that held me out of going to UofM was their stupid legal battles with my school; sometimes I hate tightass Michigan people. They wouldn't accept my credits because I was taking college classes long before I officially graduated from highschool or something like that.
But once I got into EMU, UofM started contacting me begging me to come there; WTF? They sent me tickets to a Michigan game and everything, but I was too pissed to go. I'll transfer there soon, but they really pissed me off.
