Stanley Kaplan’s version of math workbook outpaces its competitors from the Princeton Review and others. Those that are working for higher scores in math, feel relatively comfortable with math, having no math phobia, can find a good overview/review of math concepts from pre-algebra, algebra and geometry in this book. Then examples are given, followed by pages of practice of GRE-like problems that are rated Basic, Medium and Advanced. Answers are given and methods of solving are shown, though some of the really slick strategies of Mark’s course are not used for these problems. Warning: explanations of concepts here are not as in-depth ad Forgotten Algebra above or certainly not as clear as Mark’s Basic Math Refresher, but it can be a great followup to the Refresher or a workout for those already relatively comfortable with math. $19.50 includes a 10% discount, and WA tax.
