<p>What are the percentage ranges associated with all the letter grades? Sorry if I’m ignorant of Duke’s grading practices, but I’m not a current Blue Devil and I want to make sense of the grades given out ever since I read an article about Duke’s average GPAs going up for decades.</p>
<p>I know that, at my current college, A-s are awarded at 80-84%, As at 85-89%, A+s at 90%+ for instance. The scale at my own college may look a little soft but I think the coursework at my college is more rigorous than at Duke, or Tufts for that matter (per a Tufts professor that attended my college for undergrad; correct me if I’m wrong, but I do not think Duke is any more rigorous than Tufts) or else we couldn’t afford such a soft scale.</p>
