Hello guys!

So aside from my AFF life, I'm also studying for the SAT. The English section is a breeze for me but I've been struggling with math. My last practice test was 690 for English and 620 for math. I'm looking to improve both by 100 points. But it's harder for me to improve on math. 

Does anyone who took it already have websites/sources they studied from? That would be really helpful.

Thank you!!
