Sat Book Help!

<p>So I gave the december SAT and got a score of 1940</p>

<p>Critical Reading- 610
Critical Writing-670(Essay - 10)
Mathematics- 660</p>

<p>So I really want to push my scores to 2000+ and so i think i need to improve on my Critical Reading and Mathematics for I think mathematics score can be easily increased. So if anyone can suggest some books specifically for Reading and Mathematics, please tell me as it'd be great!
And oh! If you have any other tips then please please tell me

<p>Well, for math, it’s not a book, but you can go on khan academy. Amazing sat prep videos. there’s also a full practice test on there with videos explaining most answers.</p>
