I wish to boost my score a lot this summer. I am a rising junior and going to take SAT this upcoming spring. I have only taken the PSAT as a sophomore and want to raise the score drastically - 520 in math and 530 in reading (1050).
I am trying Kaplan Test Prep, Khanacademy, and other practice books. And it is slowly rising - in a recent Kaplan test I got 590 in reading and 540 in math (1130). I think this is working but is it possible for me to reach the 1400+ range in 3 months?
