3.0 out of 5 stars
I give this book a B or B-, September 14, 2008
This review is from: Kaplan GMAT Math Workbook (Paperback)
I've started studying for the GMAT last weekend and wanted one of the first things I did to be Math review. Why? I didn't want to take a full length diagnostic when I knew the results would be skewed by the fact that I hadn't looked at math problems in almost 10 years.
After a quick search, and a little online research I selected the Kaplan GMAT Math Workbook 6th edition, because it had a good mix of what I was looking for:
1. Fairly comprehensive review of the basic math concepts needed for the GMAT
2. Structure of the book allows you to work from start to finish, building on previous skills learned
3. Sections devoted to Word problem and data sufficiency questions
4. Large number of questions to practice on
After barreling through it, in one week, I would give this book a B or B-.
It did what I needed it to do. I was not gravely disappointed and I was not amazed. Some things to note:
* There were some holes in the information covered. Not the end of the world, you can find the information it lacks and you need elsewhere... online, etc.
* The book has answers and explanations for the questions on the section tests but only has answers not explanations for the section exercises which seemed like a silly omission to me for math review workbook.
* The book has a few errors. Without noticing or recognizing these in advance could throw off someone working through the book. [see below**]
Not that I have worked with any other comparable book to weigh it against but in summary the Kaplan GMAT Math Workbook, Sixth Edition gave me enough of a review of the material and enough experience with the question formats that I feel confident to take quantitative practice tests and diagnostics to start my regular study schedule.
Overall the Kaplan GMAT Math Workbook is worth getting, particularly if you feel like you haven't done math in ten years and are looking to reestablish a good baseline. Having said that if you're looking for a comprehensive Quant solution to score over a 750, this probably won't be it.
**if you decide to get the Kaplan GMAT Math Workbook, Sixth Edition here are the errors to look out for:
* p. 22, Q9 - the fraction 2/4 in the question is supposed to be 2/5 like in the answers and solutions but it's 2/4
* p. 105, Answer/Explanation 14 - in the first set of equations its supposed to say 27n = 94 to match the question, it doesn't
* p. 117, Q17 - there are two "when"s in the second sentence.
* p. 259, Q17 - Diane find that... >>> should be >>> Diane finds that [&] "more cans of" is repeated twice in a row.
* p. 332 Answer/Explanation 24 - The answer/explanation listed here is not for the listed Q24 on p. 320 in the Data Sufficiency Test One. There is no answer or explanation for the original Q24 on p. 320 anywhere I can find in the book. This Answer/Explanation on p. 332 appears to go with Q24 on p. 324 from Data Sufficiency Test Two however that question already has an answer. [see note below++]
++Note: This Q24 from Data Sufficiency Test Two already has an answer on p. 340. This answer does not agree with the misplaced answer on p. 332 that relates to the same question. In other words, this book contains no answer/explanation to Q24 from p. 320, and gives two different answers/explanations for Q24 on p. 324
If anyone knows the correct answer/explanation for Q 24 on either Data Sufficiency Test One or 2, please post it here in reply.

5.0 out of 5 stars
Maybe too optimistic, but nothing helps as much as basics, September 26, 2009
This review is from: Kaplan GMAT Math Workbook (Paperback)
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.
PROS:
- 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
- Solid 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.
CONS:
- No probability or combinations review, which would be very helpful. Get something. I bombed my probability question on the GMAT.
- 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.
- Errors (even though this is the 6th edition and it barely changed compared to the 1st and 2nd, there are a few typos and just careless errors - it's a shame)
Arithmetic
-Number operations (15 quiz questions 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)
