How can I most effectively use an MP3 player to study math for the GRE?

• How can I use an MP3 player to study math for the GRE? Can I use podcasts and other audio tools to prepare for the math portion of the GRE? For 8 hours every day, I am physically occupied but can use an MP3 player. I plan to do written problems during the other parts of the day, but are there podcasts or audio tools that would help make use of this listening time and get my skills up to speed? Is there anything else you'd suggest? I am looking for tools that will increase math skills and ideally provide a refresher of high school math in order to prepare for the GRE. More generalized math podcasts are all right, too, or something along the lines of Berkeley's online lectures. Assume that I can't use my hands or look at a book.

• Answer:

  Hmmm... It's a tough one. The best way to prepare for a math test is generally to just sit down and do problems. BUT, that said, I find it very effective to have a set of problems that I haven't solved simmering on the back burner. I think about them as I walk from place to place, and occasionally have ideas that wouldn't have come about with paper in front of me. And then I scribble them down once I get where I'm going. So I would recommend keeping a list of problems you weren't able to solve during your written practice time, and thinking about them during your daily routine. Failing that, you might also try working on fast mental arithmetic. It's not directly applicable to the GRE, but being able to calculate quickly and ballpark calculations often gives an edge in attacking a problem.
