What is the historic grade distribution?
Overall, over the past three years, about 15% of students get an A, 30% get an A-, 25% get a B+, 20% get a B, 5% get a B-, and 5% get a C-range grade. This is the distribution before the Pass/Fail grades are implemented (historically, most C grades have been among students who have taken the class Pass/Fail, not surprisingly).
