Whether you are reviewing for the SAT with a Commonwealth Education tutor, in an SAT class, or by yourself, you will always be a click away from a complete explanation of the solution to a problem with this ebook. And you won't have to lug around another huge book, just your ebook reader!

We firmly believe that any study plan for the SAT should be focused primarily on test questions from the source material, i.e, the material produced by the test-makers. We have no interest in recreating problems, but we have significant interest in providing clear, step-by-step instructions for questions that may pose problems for our students.

We have written explanations in an easy-to-understand voice, and laid out the steps for each problem. We have not cut corners; the “easy” problems (is there really such a thing?) have explanations that are just as thorough as the hard problems.

We hope you find this companion guide useful, and we welcome any and all feedback.
