Coming May 17th . . . the Official Guide Companion!


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). 🙂

    Glad to hear positive feedback on our book already! Stay tuned for a free sneak peek of our online version next week.

    Also, S Khoman, you asked about current MGMAT students. The book will be included with all new complete prep sets starting May 17, but if you would like one, you will be able to use the online OGC for free (it will be available in your student center) starting May 10th. For the physical book, please email us at to request one.

    That is simply great news . Its about time when some one did some thing , better late than never . OG is an excellent resource but I have had a hard time understanding its explanation .

    Kudos to you all MGMAT , and I hope the book doesn’t cost a fortune 🙂 .

    Great news! What about the current students of the MGMAT online course? My course just started, and will finish at the end of May. If the cost of the course stays the same, aren’t we eligible to get the OG Companion as well? I really hope so as it sounds like a very useful material.
