this document is probably worth downloading -- because all of its problems seem to be genuinely from the gmat prep software -- but, let me repeat that it is DEFINITELY AND OBVIOUSLY NOT a document of "level 700+" problems.
i actually don't understand the motivation behind labeling it as such, because it's clearly not a document that anyone is selling. (if the document were for sale, then it would be obvious why its author would try to mislead people in this way.)
the document certainly contains some problems that are quite challenging, but it also contains many problems that are clearly quite low-level problems.
ironically, this fact probably makes this document a better study source, because studying problems from a variety of different "difficulty levels" is the best strategy -- i.e., it's a big mistake to concentrate only on the highest-difficulty problems.
