One more quick aside before I continue with my Ph.D. preparation: test scores.
I finished my undergrad in 2009, and I was still considering perhaps doing some kind of math or statistics Masters Degree en route to a Ph.D. I took the GRE in January 2010 and then, because I was also considering an MBA, I took the GMAT two months later. My GRE score was about the 95th percentile, and my GMAT was in the 99th.
I applied to 22 of the top 30 Ph.D. Finance programs, and all of them accepted either test. I used the GMAT, since my score was relatively better. I did not take the GRE-Math subject test, and none of the programs to which I applied specifically asked for it. The subject test may be more useful for Economics Ph.D. programs.
