Congratulating and asking for help

First of all I would like to congratulate the people who got their dream score, and I wish the people who didn't get their dream score the best future. Second of all, I average around 1300 with the math and english being almost alike around the 650 mark. I need help with math, how can I prepare how can I practice and learn new things I finished khan academy and I'm just solving questions from the bank but is that it?
