Of course I am aware that I did unusually well, and I don't think that everyone can get a perfect score on the quant section, but last I checked, like one in 20 test takers does. To me, that suggests they could usefully make it a lot harder. Maybe I'm underestimating the difficulty of getting a 700 verbal, though. (I didn't think it was particularly more difficult than the SAT critical reading section, and I expect people to have a lot more practice reading dense academic prose at the end of undergrad than they did at the end of high school, but I can believe I'm not great at distinguishing degrees of difficulty in that range.)
