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). :)
