!HELP Best SAT PREP?

<p>I am a rising junior and I need to prep all i can for the SAT this summer and upcoming school year. Before I get all handy dandy with all these expensive books, I want some real testimonials about some book I should get. I have a lot of online sites for further help but I also want books too. </p>

<p>So far I use the Khan Academy, INAP, StudymyEnglish, VocabCoach, and PTS. This is all online and free.</p>

<p>I have the Official SAT guide from the college board and this book called the Tooth and Nail: A novel approach to the new SAT. but thats about it.</p>

<p>Can anyone please inform me about any books to get to improve my scores? My scores on each are around 580 - 600. Thanks so much! Any help or redirection will be much appreciated!!!</p>
