Number2.com is the only website that offers students access to comprehensive free online test preparation courses for the SAT, ACT, and GRE. How do we do it? Number2.com earns revenue from sponsorships and licensing.
In my search for good test preparation materials for the SAT and ACT exams, I found Barron's, which has both a free and premium option. Their test prep is customizable (love that!) and can be done on both the computer and iPad.
