What Students Are Saying: "I learned more math here than in 4 years of high school." "I like that the guides use tough examples and teach according to principles of a sophisticated curriculum, not a GMAT-for-dummies type mode." "I loved the Number Properties Guide--it was really helpful. I liked both the Manhattan GMAT questions you created after each chapter and the official GMAT questions listed in the back for more practice." "The topic by topic breakdown makes studying easy and helps you retain more information. You can brush up on your weak areas as you go through each guide." --This text refers to an alternate Paperback edition.

5.0 out of 5 stars Very Valuable Book for GMAT Prep: great math coverage and 6 full tests, November 27, 2009

By 

GMATClub.com (USA) - See all my reviews
(TOP 1000 REVIEWER)   

This review is from: Number Properties GMAT Strategy Guide, 4th Edition (Manhattan GMAT Preparation Guides) (Paperback)

I scored 750 (49, 42) on the GMAT and from experience, high GMAT score is not about tricks or solving thousands of questions - it is about having a strong foundation. Arithmetic is critical for the GMAT - close to 50% of quant questions you encounter will rely on arithmetic to solve. If you are rusty with math (primes, powers, roots, etc), this is one of the best books to refresh the basics of Arithmetic without spending months on it. Besides review, it also lists ways to save time on calculations. The faster you can do easier questions, the more time you have for the hard ones, and those are the ones that count on the GMAT.

Pros:
- This book comes with a code that provides access to 6 Manhattan GMAT tests for free ($45 value; online access)
- The book is split into 2 sections - basic and advanced, which is a better approach than dumping everything at the same time. By covering 2 separate sections for basic and then in the second half of the book advanced section, it makes you review the basics again and burns them in the memory.
- Strong section on divisibility rules (how to quickly tell if a number is divisible by 3, 4, 6, 7, etc). This will save time on the test.
- Coverage of multiples
- Primes, factoring, odd, even, positive, negative
- Powers, roots, consecutive numbers, remainders
- Bonus Question bank (online access)

Cons/Areas of Improvement
- No systematic coverage of numbers between 1 and 0 and 0 and -1, and these are some of the trickiest ones
- No strong coverage of absolute values - few of us remember how to do these
- Has exercises but relies on the Official Guide for practice GMAT questions


Bottom Line: Absolutely get this book in addition to anything else you are using. It is worth the time and money. This is one of the most popular GMAT books among the GMAT Club community and is always in the top 5 of the "Top 20 Best GMAT Books" list.

Good Luck on the GMAT.

4.0 out of 5 stars Very good for the target audience, September 18, 2007

"Very good for the target audience" - I think this sums it all. If you are someone who has not done active maths for some time now, and therefore does not remember the concepts involved very well, this is the book for you. This I will say holds true for most of the books of the Manhattan Quant series.
The Manhattan Quant series books cover the concepts only to the degree that gets asked in the GMAT, and do not overwhelm you.
Plus, as each of the Manhattan books then turns to the Official Guide for practice, each of the books has a section where the appropriate questions for that topic are numbered from the OG. They also detail the toughest of the lot from OG. Here I think the book is useful for anyone, irrespective of the personal comfort level with maths.
Therefore if you are true to yourself and practice the questions marked from OG as you go along, this would prove to an excellent resource for cracking the quant part of the GMAT.

5.0 out of 5 stars Excellent book!, January 5, 2009

By 

redpandababy (Los Angeles, CA USA) - See all my reviews

This review is from: Number Properties GMAT Preparation Guide (Manhattan GMAT Preparation Guides) (Paperback)

The Manhattan GMAT quantitative guides are great for reviewing or just flat out learning the quant concepts tested on the GMAT. Don't let the thinness of the books fool you; they efficiently pack in alot of material and do not pad the books with lots of practice questions created by them. It's far better to work off of Official Guide questions, and each Manhattan GMAT guide has a handy list of all OG questions subdivided into Problem Solving & Data Sufficiency, and further subdivided according to the concept tested. There is an additional problem set of the most challenging OG questions spanning all concepts. I am decent, but rusty at math, and after using a couple of the Manhattan GMAT quant guides, was able to improve my quant score from high 40s on practice tests to 51 on the real thing! I can't recommend these books enough.
