It’s not that absurd and happens all over the world in university systems. I had a Comp. Sci. Professor that taught assembly and graded on a curve. As you might imagine the one guy that was a wizard at assembly caught flak from the unwashed masses.

I had another professor that not only did a curve but dropped statistical outliers to prevent this problem, he literally explained his system on Day 1 of the course. This was 15+ years ago and by no means a new idea.
