What prep books should I get?

Hi I’m planning on retaking the ACT in October and taking the SAT for the first time in October also. What books do you guys recommend I get to practice for these. I want to aim high and get 2250 on the SAT and a 32+ on the ACT. Any suggestions would be nice. Should I hire a tutor? Is it really worth it? How many hours a day should I practice? For how many days? Any advice would be highly appreciated. Thank you.

check out testive.com my daughter used this…the testive pretest determines your starting level for all the review work. you can use it UNLIMITED and you are billed monthly can sign up for even one month. believe the theory is you only improve 10% on your retake SAT, unless you have massive review. good luck.
