1. GMAT Math Books1. Manhattan GMAT (MGMAT) GuidesRecommended for best results if you have the time.Strengths: 1. Good balance between test taking strategies and background theory explanations

3. Covered concepts are illustrated with examples that are conveniently assigned to either PS or DS section.
4. Access to 6 Online CAT's (same for each book)
5. Additional online practice question banks (different for each book)
Weaknesses:1. Time and Money
2. Books themselves do not contain many practice questions (though online and
OG 12 references more than compensate)
Notes: most often recommended guide is the
Manhattan GMAT Number properties and
MGMAT Word Translations
2. Veritas Prep GuidesRival of the MGMAT bundle though a bit higher priced.Strengths: 1. 12 total guides + an intro book for quant + test simulation booklet
2. Practice questions. Every one of the guides is packed with practice questions
3. Fresh questions; you probably have not seen them on forums/etc since these books have just been published
Weaknesses:1. Spacing is a bit strange sometimes with only one question per page
3. Kaplan GMAT Math WorkbookA solid supplement to the Official GuideStrengths: 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
Weaknesses:1. Statistics, Combinations/Permutations and Probability are not covered
2. Questions do not reflect GMAT questions, but rather are designed to insure that the material is mastered
Notes:
Recommended/most interesting problem compilation from Kaplan Math WorkbookFaster than going through the math
MGMAT Guides, but also not as thorough
4. Official Guide for GMAT Quantitative Review Great for additional math practice questions, but don't expect to find any strategies or math lessons here.Strengths: 1. 300 real GMAT questions
2. Real GMAT questions retired from past tests
3. The practice questions are organized by level of difficulty
4. The practice questions follow actual GMAT test patterns  great to have one's ear trained.
Weaknesses:1. The book does not contain any strategies
2. It does have a few short review sections but they are very weak
3. Mostly easy and medium difficulty questions. Not very helpful to a person aiming to get above 700.
Bottom Line: this book is optional; usually the
OG is sufficient by itself.
5. GMAT Club Math Book 120 pages covering some of the trickier and harder topics such as Number Theory, Probability, and CombinationsStrengths: 1. It is Free!
2. Has sample and practice questions
3. Extensive explanations and support on the forum
Weaknesses:1. It does not have some of the more basic topics and has multiple authors so the flow is not ideal
2. You will need to find more practice questions
Bottom Line: It is free, and has solid content from GMAT Club's brightest minds
