Top Customer Reviews
- 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.

I wasn't going to buy the whole series but was so impressed by the first book I used (Sentence Correction), that I bought a couple of the quantitative prep books. I was so impressed by those, that I ended up buying all the rest of them. I can not stress enough how much more focused and useful this material is than Kaplan. When used in conjunction with the Official Guide, you have everything you need to break 700.
The things these books provide make so much sense as the best way to prepare, that it makes you wonder why everyone else doesn't do it. My guess is that Manhattan benefits from a focused business model of limiting itself to the GMAT. If you're not looking to score that well and only need to practice some and get used to the questions, the Official Guide is enough. But the Manhattan series is also nice in that it allows you to pick and choose the certain topics you need extra help with. Also, by only buying one book, you get access to six practice tests that are very difficult and provide invaluable information in its readouts of your performance (much more detailed and useful than Kaplan's. Hate to keep hating on Kaplan, but it's the only thing I have to compare to. It's not horrible really, it just pales in comparison to Manhattan. I think of the Kaplan material like I think of McDonald's, very well-known but pretty junky. It'll fill you up, but you won't feel great afterward...)
I've never taken the time to review any items on Amazon.com before, but I have been so impressed with this product that I felt compelled to let others know about it.
Don't waste your money on a class, get the Manhattan series instead. You'll save over a thousand dollars and be better prepared as well!

CON: Not free. I didn't buy it before taking my 1st test. (Scored 480 and studying for 2nd test)
