Need help on reaching 2100+

<p>I took the SAT two times already, but I'm not doing very well! :(</p>

<p>March'11: CR 590 M 680 W 700 (essay 8)= 1970
June'11: CR 650 M 610 W 720 (essay 11) = 1980</p>

<p>I know I'm not even breaking the 2000 barrier, but hopefully I can do even better with everyone's help! My grades are fluctuating on CR and M. I self-studied some more on CR in the time between the two tests, but still! On math though, I thought the math in the first sat test was harder! I don't know how to study for math when I feel like I know the stuff but still get such a low score! ;_;</p>
