Law school or really any graduate school. It's kind of laughable that we still rely on GPAs. The solution would be to convert college grades into a kind of item response theory measure of fitness for each student (equivalent to like the degree of difficulty of test questions). You could do it within a school so that you can create a better measure of ability that controls for difficulty of majors or individual classes. You could create one nationally as well, though getting data combined together would be a pain. Something like SAT/ACT/GRE scores might help when comparing between schools. Or grades of students who transfer schools.
