This may be a dumb question, but are there questions in the 11th edition of the OG that are not in the 12th edition? Or is the 12 edition basically the 11th edidtion with new questions?
I am trying to find new RC and CR questions as I am on the verge of my 4th GMAT attempt and I have been through the OG 12th
edition twice, and both supplements (1st editions) twice. I am going to purchase the verbal supplement (2nd edition,) just because there are a few new questions in there, but was wondering if the 11th edition had any exclusive material?
