So I took the GRE yesterday, in Taipei. It was surprisingly easy, except the part where I had to get there by 8:30 in the morning, requiring me to be on the bus at 7:15 or so. It was kind of an interesting feeling, I really haven't done a standardized test in a while, so being surrounded by about 500 people who are really nervous, just like you, was kind of a nostalgic feeling. The test confirmed for me that I suck royally at math, I had forgotten pretty much all of the equations I ever learned, but since it's really not all that important for my field of study, I didn't really care. I had about an hour of being bored and then an hour of stress, bored=math stress=verbal. Incidentally there was one guy who was clearly drunk when he was taking the test. I guess he was either really confident or really dumb. I'm not really sure which.
Also, an interesting aside. I only realized at 10 pm the night before the test, that I had no pencils. Or at least no mechanical pencils. So I ran around like an idiot for an hour the night before the test looking for pencils. Apparently they sell pencils specifically designed for computer test taking in 7-11. Truly this is a wonderful country.
