This "It is still very hard to get into elite schools, but it's not at all difficult to graduate." needs more nuance. My daughter could tell you it isn't easy, at all, to graduate from CMU SCS. It will kick your ass no matter how smart you are. That said, of the entrances to any program that's highly selective on a relevant basis, wouldn't you expect almost all of them to graduate with a good GPA? There a lot more diversity of ability at programs with 30% acceptance than 3%. Grading on a curve might work there, and be a factor in motivating students to work harder. But is that the best approach? Would ending legacy and donor admission concessions do more for academic rigor?
