Kaplan GRE & GMAT Exams Math Workbook : Fourth Edition (Kaplan Gre and Gmat Exams Math Workbook)

Rating:
Summary: Maybe too optimistic, but nothing helps as much as basics
Review: I got 99th percentile on my GMAT 750(49, 42) and i used 3 books: this one, Kaplan's book with CD and Verbal Workbook. I had access to PR book and PP, but I did only tests from those. I found Kaplan's materials of quality and difficulty. Some whine that Kaplan is too hard, but that's good - if you can handle Kaplan, you can handle old good GMAT.

My favorite things about this book:
- Very short and condensed math reviews - straight to the point
- No smart-aleck advice about some stupid tricks - only math review - exactly what I needed
- Fabulous problems that illustrate a lot of traps and multiple ways of solving them
- Starts with the basics - arithmetic, integers, primes, etc - the stuff that anybody can uses a review of. A lot of applicants underestimate how much they forgot the basics and skim/skip them. I would not do that, and that book does not either.
- Finally, the number of questions and quizzes in this book is impressive. I am giving a short summary of some of the sections of the book and number of quizzes and test questions. Quiz questions are math only; Test questions are GMAT-type questions.

Arithmetic
-Number operations (15 quiz questoins and 15 test questions)
-Number properties (15, 19)
-Averages (10, 19)
-Ratios (10, 24)
-Percents (25, 25)
-Powers and Roots (12, 17)

Algebra
-Level One (20, 26)
-Level Two (15, 15)

Word Problems
-Level One (10, 26)
-Level Two (37)
-Test (40)

Geometry
-Lines (6, 14)
-Triangles (16, 21)

-Quadrilaterals (15, 19)
-Circles (19, 13)
-Multiple Figures (4, 15)
-Solids (6, 8)

Data Sufficiency
-Test 1 (25)
-Test 2 (25)

CONS:
- I went through this book at least 3 times (helping others) and I found that solutions don't include some of the most genius ways to handle the problems. I think the authors of the questions went beyond themselves.
- No probability or combinations review, which would be very helpful. Get something. I bombed my probability question on the GMAT.

Summary: Excellent but incomplete
Review: Kaplan's Math Workbook clearly explains most of the math skills tested by the GRE and includes a large number of practice exercises in all areas and at all difficulty levels. What's more, it guides you incrementally from the easy to the hard, so even the math-phobic will find it approachable. It's main flaw --inexplicable, inexcusable and potentially dire--is it's lack of probability and coordinate geometry review. Both of these concepts will be on your GRE exam and if you don't review them from another source source, you will be underprepared. Overall, though, it's an excellent book.
