Best Math SAT book to raise a 630 to a 700

<p>I've been looking for a good SAT math book, but there are so many different books. Each book has their drawbacks. In your opinion, what is the best one for me.</p>

<p>I would recommend grubers.</p>

<p>Dr. Chung when you score above 650.</p>

<p>And what if you scored 650? Is Dr. Chung’s book still recommended?</p>
