From the Back Cover
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."

About the Author
Manhattan GMAT's 8 preparation guides were developed by Manhattan GMAT's talented staff of real teachers, all of whom have scored in the 99th percentile on the official GMAT. As the company focuses solely on the GMAT (no other tests), it continually updates the guides to reflect the GMAT's most current trends.

Customer Reviews

Very good for the target audience
"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.

Excellent book!
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.

Really impressive and very neccessary
GMAT has been getting more difficult over the years. If you have any doubt, take the GMAT Prep (just google it) and compare the level of difficulty with the Offical Guides. The difference is very substantial.

Unfortunately, most GMAT prep companies, includng MGMAT, have been behind he curve of the changes.

But you are in luck as this new MGMAT book succeeds where other books, includng the previous edition of MGMAT number properties book, have failed. This new edition provides a very comprehensive explanation of GMAT number properties (primes, odd and evens, postive and negative, consecutive intgers, exponents, roots etc) which the previous version was lacking. Most importantly, this book is far better at emulating the difficulty and types of questions of the current GMAT test.

Number properties is perhaps one of the most difficult components of GMAT Quant section. Although GMAT tests only high school math, do not mistake its quant section for an SAT. For example, how many prime factors (odd or even) does a perfect square of an integer have? Can you find the total number of factors (not just prime factors) of number 2000 in under 2 minutes? Even if you are good in math, you probably can't without the help of this book. And yes, GMAT does ask you such questions which you should answer in 2 minutes or less.
