Not much different from 1st Edition - 28 new hard questions, September 4, 2009
This review is from: The Official Guide for GMAT Quantitative Review, 2nd Edition (Paperback)
There are 44 new Problem Solving and 31 new Data Sufficiency Questions (a total of 75 new questions out of 300).

--- List of Changes:---
Problem Solving (PS)
- 4 new easy questions
- 21 new medium questions
- 19 new hard questions
Data Sufficiency
- 13 new easy questions
- 8 new medium questions
- 9 new hard questions

The main issue with the first edition was low question difficulty. This edition addresses the issue slightly, but as you can see, not by much. One issue that was fixed is the total number of questions. The first edition claimed (just like this one) to have 300 questions, but only had 294 - how can you make that mistake in the Official Guide for Quantitative Review? The question split is 176 for PS and 124 for DS.

As to content, changes, it is interesting to see many of the tables and data-interpretation questions go and addition of sequence questions. Also, DS lost many of its arithmetic questions, which were replaced by Word Problems.

Overall - pretty much the same book - would have loved to see more new questions, but \$12 for 28 new hard and 29 medium REAL questions is not bad. By the way, the first edition is on sale right now The Official Guide for GMAT Quantitative Review for \$6.78!

Here is the full list of new questions for reference:
PS: 1, 2, 7, 41, 56, 60, 61, 62, 64, 67, 68, 69, 70, 71, 72, 78, 79, 80, 81, 83, 102, 103, 108, 112, 117, 131, 135, 142, 145, 146, 147, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 160, 162, 173

DS: 1, 6, 7, 9, 11, 13, 14, 16, 21, 22, 24, 31, 33, 43, 48, 51, 66, 70, 73, 79, 82, 85, 96, 102, 104, 106, 107, 111, 116, 117, 122

Hello! Thank you so much for all that work you've done and insight you've provided! Your opinion has helped many I'm sure!

I am planning on getting the Manhattan GMAT books after reading all the good stuff you said about them. However do you think the 2007 edition varies a great deal from the 2009 editions that I should get the 2009?

Thanks for all that you do!

If you already have 3rd edition, there is not much value in getting 4th. (Though i hear the SC book has been beefed up with more idioms and examples). The main difference is the additional practice from OG. 3rd edition refers to The Official Guide for GMAT Review, 11th Edition, whereas 4th edition is pretty much the same book but with references to The Official Guide for GMAT Review, 12th Edition. There is a document available from the Manhattan GMAT's website that helps owners of 3rd edition use OG 12 and vice versa. Also, both math and verbal books in 3rd and 4th edition refer to the First editions of the Quant and Verbal Official Guides. If you are buying second edition (this book), also look up Manhattan's website for a conversion document.
