It’s worth noting that these numbers are for the Class of 2019... Reddit is compiling numbers for the Class of 2020 as they’re published https://www.reddit.com/r/lawschooladmissions/comments/6u4ceb/class_of_2020_medians/
It is hard to see that if HLS, Columbia, Northwestern take GRE that the Penns, UVAs, NYUs will be able to resist. Perhaps YLS and Stanford will hold out, but I bet everyone from Columbia on down goes GRE.
Yeah, I agree with the above posters. Accepting the GRE will get Harvard more applicants, for sure. But, where is it written that they will accept even one of these GRE applicants? It could really just be a way to goose yield as HLS slipped a notch.
