Want to try before you buy? Go right ahead! I'm making the chapter on Ratios available for free. Click here to read it!
Every chapter—including the Ratios chapter available here—is followed by several drill questions designed to see if you understand the basic concepts. Then the book gives you several (usually about 5) realistic GRE practice problems, including both Problem Solving and Quantitative Comparisons. Full explanations for all of those problems are included in the back of the book.
