The 12th Edition of the Official Guide for GMAT Review is an awesome resource, likely the best available, and we heartily recommend it to all of our students. Indeed, the Official Guide and its supplements are included with all of our courses and form the core of our curriculum.

However, if there is one weakness that students often cite, it is that the Official Guide’s explanations are sometimes confusing and/or unhelpful, particularly on some of the math problems.

To address this need, we are very proud to announce the imminent publication of the Official Guide Companion! This book includes thorough, step-by-step explanations to every math problem in the Official Guide, using the principles of our curriculum for consistency. Problems that customarily give students headaches are flagged as part of ‘Horacio’s Hotlist,’ named after ace Instructor Horacio Quiroga. There is also an online version of the OGC for easy reference.

Note that all of the referenced questions appear in the Official Guide itself, which is necessary to make use of the Official Guide Companion (hence the name).

All of our course students will begin receiving the book May 17th, as part of their course materials free of charge. The online version will be active one week earlier, on May 10th. It’s good to be one of our students!

Thanks to Chris, Dave, Carrie, Graham, and all of the other Instructors that worked so hard to make the Official Guide Companion possible! Many students are about to have a problem solved (pun intended). 🙂

Following up on the release of the 12th Edition of the Official Guide for GMAT Review, GMAC is now releasing the 2nd editions of both the Official Guide for GMAT Verbal Review (released this week) and the Official Guide for GMAT Quantitative Review (to be released in the next couple of weeks).

As was the case with the 12th Edition, we will be breaking down the new guides in detail.  As a preview, 81 of the 300 verbal questions in the 2nd edition of the Official Guide for GMAT Verbal Review are new, in that they didn’t appear in the 1st edition or the Official Guides.  That means that 219 of the 300, or 73%, appeared in the 1st Edition of the Official Guide for GMAT Verbal Review.  We’ll be analyzing the 81 newbies in detail later in the week.

Among the many topics of discussion at the Manhattan GMAT Instructor Convocation was what happens to the 11th Edition of the Official Guide now that it’s about to leave print.  Here at Manhattan GMAT, we have something of a library of the various editions of the OG, starting with the 4th Edition or so (our copy of that one is pretty tattered).

Most students automatically gravitate toward the 12th Edition of the Official Guide for GMAT Review as soon as they hear about it, because, well, the newer the better.

But the fact that the 12th Edition is one-third new questions also means that the 11th Edition has several hundred other fairly representative problems of recent vintage for the thorough student to pore through.  So if you’ve got Big Orange lying around, don’t punish yourself for having an earlier edition.  Instead, praise yourself for picking up what could soon be a Collector’s Item.
