I am purchased this book about four- five weeks ago. This book has been easy to follow with well explained examples. Each chapter has questions divided into easy, moderate, and advanced difficulty. I am pleased that i could answer the majority of the questions with ease. i do however feel that the actual test will be much more difficult, and I am going to purchase another book to get a comparative source. i do believe this is a good starter book for those who might be fearful of Math, but that it would not be wise to take the test after only reviewing this book. Again, this book was excellent, but I would reccommend purchasing several other sources to use as well.

I studied for the GMAT for 3 months and scored a 680 -- 90th percentile. My quantitative score was a 41 (64%) and my verbal was a 42 (96%). I decided to pound math for another five weeks, retake the GMAT and try to close the gap between my verbal and quant scores. After using this book and studying nothing but math for another month, I scored a 710 (94%). Quant was a 42 (66%) and verbal was a 46 (99%). I actually increased the gap by one percentile point! Doh!

Feel free to draw your own conclusions from this. Math has never been a strength of mine, but I expected a better quant score after studying the quant side of the exam exclusively for five weeks.

I think this is probably a fine book for teaching the very basics, but I needed help with probability and permutation problems and others that this book doesn't even touch. I was kind of disappointed that it didn't go deeper. If you purchase it, definitely pick up another text that will give you a more rounded idea of the types of problems the GMAT asks. The Official Guide is invaluable and I learned some great test-taking strategies from the Princton Review's "Cracking the GMAT" book. Overall I'm very happy with my score, but still a little frustrated about the math. I'm sure you'll do better. :-) Good luck!!

To be honest, i have not actually began using b/c i will not take the gre until march. have glanced through and seems sufficient.

I went through this book for the GREs and did better than I ever have on a standardized math test. So it is useful if you just need to review basic formulas. One thing that bothered me, though, as an indication of shoddy publishing/editing, was that I'm pretty sure they gave the wrong number for an answer in one of the early chapters. I also found several typos in the book. I hate Kaplan and the ETS for making so much money off students with their false promises of "invest thousands of dollars on this stupid, irrelevant test, and you will score better, even though the test is not a true measure of intelligence". So you'd think that as an educational guide they'd at least make sure all their answers were right and all their words spelled correctly, so they could at least pretend their product was worth buying. I'm glad I only spent 7 bucks on it.

Before buying the book I got in the 10 percentile on my first crack at the actual exam, after buying this book and using the Kaplan CD tests I got in the 65 percentile on my second attempt. Consequentially I would say this book is good for people that are not strong in math. It will give you the basics you need for an average score. If you're looking to get into the top 80 - 90th percentiles in the quantitative sections this book will be of little use to you.
