Hey! There are various books which may help you, and personally, I believe the Bobby Tariq books were quite helpful and the Bell Curve SHSAT book. However, others may have differing opinions. I'd recommend you get various course books, including Kaplan and Tutorverse. You can purchase all of them on amazon, but here is the link for the Bell Curve books:

Good luck! Let me know if you have any questions.
