Just got my SAT scores....

[Shuffler]

540 in math is kind of low hate to say it  but even I got a 620 and  never took higher than algebra I. I suppose talking my way into Physics and  Honors Physics  helped(its all the same maths)

My youngest took her SAT the first time back in grade school (5th or 6th grade) and tested higher than 80% (IIRC) of the college bound students.

Yeah, I tend to get screwed over by the trick questions and such. 5 minutes before the math portion ended, i went back and checked my answers, and I realized that I had screwed up on, fallen for tricks on, or simply missread about 7 questions. I only had time to go back and fix 3. And thats only the ones I caught.

You're obviously a bright kid so it shouldn't be too hard raising your math score, I encourage you to look at khanacademy or just pick up a calculus text book and start teaching yourself.  I don't think the SATs require calc knowledge though, so a better use of your time might just be to practice SAT type math questions, get familiar with the types of problems they'll throw at you.
