That is an important point that I am glad you made. When I attended GU Law, and I presume it continues today, grading was blind. You had a number or code on your test, and the teacher had no idea who you were when grading the test. Results were posted in those days outside the classroom, by number, not name. The only exception to that system would be if a class required a written report, but nowadays, that could be kept anonymous, too. As a result, it would be impossible for this professor to discriminate against any particular race, at least in connection with grading. I am curious how she knew who were the lower ranked students.
Blind grading continues today:

“As a result, it would be impossible for this professor to discriminate against any particular race, at least in connection with grading.

I would love to better understand how she knew the class rank of the black students or was this available after grading? Blinded merit based grades are a real measuring stick that isn’t racially tainted.
