The University of Michigan is moving away from traditional letter grades for incoming freshmen. Still, 32% of college students continue to experience moderate to severe anxiety symptoms, and many experts believe that reducing grade pressure could help. The shift at Michigan comes amid broader debate about grade inflation at American universities. In May, Harvard University faculty voted to cap the number of A grades per undergraduate course at 20%, an effort to address grade inflation from the other direction. Derek Peterson, a history professor and former faculty government chair at Michigan, told The Wall Street Journal that the strategy gives students room to explore.
