Well sure, but the relevant question is whether a touro grad with a 3.85/35 is much worse off than someone from YU with the same numbers. And from what I understand, the answer is that any difference is much less substantial than the difference between the schools might suggest.
And your reference to law school proves the point. Because if there really is a strike in law school admissions against BTL’s, everyone agrees that there is no strike against Touro or any marginally normal college.
The reason you see great colleges represented in prestigious graduate schools is that students from those colleges are the ones who score high on the admissions tests.
