SAT Math Prep Book

<p>I performed horrendously on the PSAT in math. I got a 39. I take honors math classes and I have always gotten A's in math yet I failed miserably at the PSAT. I'm taking the June 7th SAT and though it will be my baseline score, I still want it to be a heck of a lot better than my PSAT math score. I want to know what the very best math SAT prep books would be for me. I probably need to read both the easier and the harder level ones but please recommend some because as you can see, I REALLY need to increase my scores.</p>
