Can somebody please suggest the release date for OG 14th edition?
I would start my GMAT preparation in April, 2013. Pl guide if I should wait for the 14th edition or buy the 13th edition and have it done with.
These books do not come out annually.
11th edition - 2005
12th edition - 2009
13th edition - 2012
This most recent version came out mid-last year. It is still very up-to-date. Even the 12th edition is a valuable resource (13th has a bunch of new questions and the IR section).
The 14th probably won't come out for another 2-3 years.
Good luck with your studying!
