New Editions of Supplemental GMAT Official Guides

More new editions. Earlier this year, the GMAC (the makers of the GMAT) released the 12th edition of The Official Guide. Now, they've updated their two supplemental books, The Official Guide for GMAT Quantitative Review and The Official Guide for GMAT Verbal Review.

The GMAT doesn't change very much over time, so if you've been using the earlier editions, don't fret. If you can handle the material you've been studying, you're well-prepared for the exam.

In fact, the differences between the 1st and 2nd editions of the supplemental guides are tiny. According to the publisher, each book has 75 new questions out of a total of 300. The newcomers don't indicate any major new trends.

If you're absolutely fixated on seeing every possible GMAC-published question before you take your exam, you'll need to get these books. Otherwise, they are a very minor addition to your study arsenal. Take it from an expert: Feel free to stick with the books you already have.

About the author: Jeff Sackmann has written many GMAT preparation books, including the popular Total GMAT Math, Total GMAT Verbal, and GMAT 111. He has also created explanations for problems in The Official Guide, as well as 1,800 practice GMAT math questions.
