#### Is OG11 a subset of OG10 (SC section)

Fri Jun 08, 2007 7:03 am
Having completed SC section of the OG10, I was browsing through the same section of the OG11. I found that several question were repeated, and as number of SC questions in OG10 are far more than in OG11, is OG10 a superset of OG11 ?

Further how does the same question goes for the RC and CR sections.

There is some overlap, but OG10 is not a superset of OG11. Do some searches on the GMAT Strategy forum area--there was some discussion a while back about overlap between OG 11 and OG 10.

OG10 and the three new OG books (OG11, verbal supplement, and quant supplement) overlap by about 75%. That is, about 25% of the questions in OG10 were discarded, and about the same number of new questions was added to the three new books. So, yes, there is significant overlap, although there are some new questions in the new books.
