Welcome back to the US! Good luck with your goals. I think you will have an easy time with the GRE, just grab one of those books (I used the Princeton Review book) and spend some time learning how the test works and how to beat it. Frankly, I think you could take it cold and do well.

If you are taking the GREs in December, does that mean you are applying for programs this Fall/Winter (to begin study next fall)? If so, we can be application buddies. What do ya say? Want an application buddy?
