When I checked the rankings, they said ASU Main sucked. I, too, was unable to get ASU West. Well, I took it there anyway, and it was awesome. Only 20 or so people were there, and we had those library cubicles as our desks (look at the banner that says 'time to move on'...it's the desk on the far right). Everything went quickly, we didn't have to compete with a mob of people for the bathroom or vending machines, and the desks were huge (even compared to the pic I referred to).
Out of curiosity, where are you taking your test?
