How to drastically improve math SAT?

<p>I have a 600 in math on the SAT (740 in CR and 790 in writing).
I want to get my math score up to 700 by October...any tips on how I can do this? I've been trying to fit in a lot of practice tests over the summer (tough to balance with summer hw--I'm going into IB 2).
How can I improve my scores?
Thanks for any help!</p>

<p>Try some AMC8/10/12 problems.</p>
