I'm looking for a book or a downloabable list of the more difficult GMAT math questions. The questions I'm getting in the OG and the Quantative OG arn't nearly as difficult as the 700-800 level questions in most of the practice tests. I'm getting close to 75% correct on the 600-700 questions, but missing the majority of the 700+.
Any suggestions on a book to buy or something else?
