Mathematics GRE

Does anyone recommend any of the more "advanced" schaum's books such as Topology, Advanced Calculus, or Probability and Random Processes (among others)?

I need to work more problems and are wondering if any of the Schaum's books will have material parallel in difficulty to this subject test.

Grazie!

I found Shaum's Outlines very useful. In particular I would recommend their "General Topology" book (by Seymor Lipschutz), which has a lot of problems and materials quite close to those being tested on the real test.

Thanks!
