Half price is still $75. If I had the same financial situation as when I came into undergrad, this still would have been prohibitive. Also, the fee reduction voucher took 4 weeks to get, after which you could call and schedule your appointment. Because the test centers fill quickly, this requires a lot of careful planning. They seriously need to revamp their program for the underprivileged. I think in general, the GRE is helpful. I'm glad my performance from a large public university, which curves most classes to a 2.8, can be compared to, say, an Ivy League with massive grade inflation by another means than GPA. I will admit that it is probably a better measure of how you perform under stress than anything else, but isn't this still a good number for adcom's to keep in mind? You are a candidate for a stressful program after all.
