What is hands down the best SAT book for the math section?

<p>I've been on several threads trying to figure out which books are really worth buying in order to improve your math score. Sadly, there are so many opinions out there that they all seem contradictory. Some say dr. Chung is the best math book while others call it trash because of typos ect. Which books would help me individually go from a 710 to an 800 other than the blue sat book?</p>
