I’m taking the November SAT and currently trying to prepare using different prep books. How would you rank the similarity of the test questions (and general helpfulness for) to the actual SAT from these brands: Barron’s, Princeton Review, Kaplan? Like if I were to take a practice test from one of these, which one would be the best indication of my score? Also, how many full practice tests do you think I could cram in before the SAT without making it futile?
