I have the official guide for gmat quantitative review 1st edition
and lately I brought the OG 13th
Also, I brought the Manhattan books
on Quants.(5th edition)
At the end of each Manhattan book, there is a sheet giving the pages and the question number from OG 13th
the official guide for gmat quantitative review 2nd edition
..............now, is there a list of common problems in the 1st and 2nd edition....or are the question number ref. same in both the books??
How much would I miss in case I don't buy the 2nd edition...( I don't want to buy another book on quants!!)
Please let me know.
