Newmark's Door

Yascha Mounk, Associate Professor of the Practice of International Affairs at Johns Hopkins, proposes a system "much better than the status quo". 

While I completely agree that grade inflation is a deadly serious problem in education, I think his proposal wouldn't achieve most of which he claims for it. I think that the one relatively modest advantage that he claims that would actually result is "Stop creating a disincentive for students to take the most demanding courses or taking advantage of the full variety of course offerings at their universities."

To paraphrase Chief Justice Roberts: if you want to stop grade inflation, stop inflating grades.
