Number Properties GMAT Strategy Guide, 4th Edition (Manhattan GMAT Preparation Guides)

I didn't take a class, but I have alot of friends who have and have used the Kaplan book and practice tests in addition to the Manhattan. Manhattan prep material and tests are head and shoulders above Kaplan. My only wish is that I had started with the Manhattan series and not even worried about Kaplan. Kaplan may have the brand name, but the fact that Manhattan focuses only on the GMAT shines through. The material goes wayyy more in depth, and it really leverages the other best source of practice material you have, the Official Guide (it has a great feature called rephrasing that references the OG problems directly to give data sufficiency help. It almost makes so much sense that it seems obvious but ingenious at the same time. Why not use the actual old test problems provided by the GMAC as much as you can?).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!Good luck!

I studied alone for the GMAT and used the manhattan GMAT reviews and the Official GMAT review books to prepare for my exam. This one out of the series is by far the best. It gives you the tricks you need to attack certain problems that keep coming up on both sections of the math. I also liked the six free of charge online exams that are included with the book. For this price you cannot beat that!

Yesterday my package arrived opened. Only book 4 was inside the package but book 1 was nowhere to be seen. I waited a day to see if maybe it’ll appear but It didn’t. I really need the book since I’m taking the test this upcoming week. Hopefully, something out can be worked out.

What I especially like about this GMAT prepbook is that it explained Number Properties in a non-complicated way and I learned properties that I had never learned when I took Algebra or other math courses in college that is essential for the GMAT. For example, the rules of counting and summing large consecutive numbers and multiples. If you don't know these rules and the rules for finding multiples and factoring quickly you won't be able to perform well on the exam.***Please excuse my grammatical errors***

This stuff isn't taught at high school or college. I learned soooo much from this book, it's just amazing.CON: Not free. I didn't buy it before taking my 1st test. (Scored 480 and studying for 2nd test)

This book covers well the concepts and has several advanced exercises of this part of the Gmat. Buying the book, you will have access to 6 online GMAT tests. The online tests are really good and come with detail explanations. The level of the questions in the online exams is higher than in the real exam.

Like all the other Manhattan GMAT materials, the indepth coverage of the topics gives the test taker a huge advantage over others who used more generic prep materials like kaplan. Don't buy kaplan!!!!!!

Great kindle version. Only flaw is that the formulas are garbled up on a few pages. The kindle (or iPad) may incorrectly have a '-' sign where a division sign should have been. As long as you're aware of that, you'll be fine. This beats carrying around the heavy print edition.

If you already have strong math skills, this book may be too basic for you but still good as a refresher. However, if you are like me and didnt pay much attention back in school, this book is a God send. Cant recommend it enough. Its not a heavy book ,so doesnt put you off. The contents are very clear and concise and the best part is that they try to explain the same concept in several different ways which helps you understand how GMAT may phrase an easy question in a difficult. Very good coverage of basics especially for roots and exponents. Practice questions are available online, but you do need to get hold of the OG 12th edition and GMAT Quant review as this book doesnt contain the questions but suggests which ones you should do. Good Luck!
