For example, there are different SAT prep books and practice test books by Princeton Review, like "Cracking the SAT Premium Edition with 7 Practice Tests, 2018 ". and “9 Practice Tests for the SAT”. I wonder if I’ll get 16 practice test on buying both of them or there is a repetition of tests in the books by the same publisher. There are similar scenarios for Barrons and Kaplan. Please Help! Its sort of urgent.
You should consider more niche services for the SAT by people who are actually high scoreres. Check out college panda and Erica Meltzer if you want books. If you want to prep online check out Uworld (there is a link for free 90 days in Reddit).
