We've recently gone through several editions of MGMAT guides
because we want to stay up to date with the OG guides:
The GMAC came out with their 12th edition last spring, so we moved from 3rd edition books to 4th edition books (you can see the differences here: http://www.manhattangmat.com/fourth-ed-info.cfm
The GMAC then came out with 2nd edition guides for verbal and quant review in the fall, so we updated our books to the 4.1 edition this past winter. The only difference between the 4 and 4.1 is in which OG books they reference. The content is the same.
We're constantly responding to feedback and trying to create better guides, so we we are planning on updating our books again, but they shouldn't be out for about a year, so your best bet would be to get our 4.1 edition guides with the 12th edition OG and the 2nd edition OG quant
and verbal review.
Let me know if you have any questions!
