So I just bombed my GRE: 700 verbal, 660 math. I don't know the exact percentile of each, but I know its low, especially the math. How do grad schools handle re-tests? Do they just look at the highest one, like most undergrad admissions offices do? Do they average the two, like I think I heard somewhere they did? Something else? Is it worth taking them again, or should I just kiss grad school goodbye and get on with life?
