good luck... I took mine last Friday because I scheduled my appointment last Monday hoping to get an appt before they change the test on Oct 1st... don't worry, it's not too bad... as a typical engineer/computer scientist, I did way better on my analytical and quantitative than on my verbal

One tip on the analytical though- make sure that you get the beginning questions correct. I was told that those are what count the most, and if you start running out of time, just start guessing. Again, good luck and don't worry... I winged it (well, I took a few practice tests, but that's it) and did pretty well.
