I am currently trying to study for the SAT that I will take this December and would like to have a boost from a 1330 (practic) (620 CR, 710 M ) to at least 1510. I know it is a huge jump, since my CR/W score is currently sabotaging me from getting a higher score. My math section would just require a lot of practice, since I do not lack in the material but just the practice. Is there any good books for improving my essay and my CR/W section? Thanks!
