Fractions, Decimals, & Percents GMAT Preparation Guide, 4th Edition (Manhattan GMAT Preparation Guides)

$9.99

This book can be valuable to those who never did well in grammar school and high school arithmetic or to those whose rudimentry math is extremely rusty. The book covers the simplest portion of GMAT quant section(fractons, decimals, percents). As its name implies, this book covers mostly rudimentry arithmetic which is sure to bore many GMAT takers.

I have found only 7 questions which I personally found somewhat challenging. Worse yet, the real GMAT questions are signficantly (but not substantially) more difficult than the questions presented in this book.

Still, this book provides valuable review of arithmetic. I was going to grant this book 4 stars but the explanation of the answers were really dumbed down to those who would have trouble with rudimentry arithmatic. Given that I could solve most of the problems in this book in my head, I have found book's advocacy of grids to solve basic arithmatic problems to be counterproductive.
