Guide to OG: 12th Edition Update

June 05, 2009

I'm happy to announce that I've updated my Guide to the Official Guide to reflect the content of the 12th edition of the GMAC Official Guide to the GMAT!

There are over 100 new practice math problems in the 12th edition that did not appear in the 11th edition, including a large number of new Data Sufficiency problems. My Guide to the OG now includes explanations for every question in the 12th edition, both the new problems and the recycled problems from previous editions.

You can read all about my Guide to the OG by clicking here. You can read my review of the 12th edition itself here.

If you don't already have my Guide to the Official Guide, this is a great time to purchase. Get a no-nonsense explanation of all 452 quantitative problems in the 12th edition, lists of questions by difficulty level and content area, plus all of that information for the 11th edition, as well.
