I'm looking for a good set of practice problems with explainations. Preferably a specialized one for both PS and DS. I'm looking at something in the 720+ difficulty range. Anyone know of a book out there?

Are there other sources that include TOUGH Quant GMAT-type problems. Its important that they are similar in diffculty to the GMAT.

Some guy named Jeff Shullmann (something like that) has some 100 DS problems. Anyone use them?
