Math Help!

<p>Hey you guys. I have really good CR and W scores, but my math score is a terrible 580(!)
I'd just like to get it up to at least 640 but preferably better. Ive practised a lot. I know some of you out there improved your scores by more than 50 points!</p>

<p>Please, do you have any advice on what helped you improve?</p>
