There are a wide difference between the very GMAT test and the 12th edition. According to my statistics, the 12t Ed OG is only relevant for the 72% of the actual GMAT test; meanwhile, the 11th Ed OG is 78% accurately, but the 6th to 10th are almost the 82% of the actual GMAT test.kevincanspain wrote:What do you find disappointing about the 12th Edition?

I teach for the GMAT since 1994 and I have all editions form OG and all the possible "old" booklets since it was paper base test. 12th edition not pass the test by other OG editions....
