I wonder how many picked OTHER THAN an A?
I ran into a silly situation when I was getting my masters degree in the 1970s. The prof believed that everyone can and should achieve everything they want to achieve. So, he gave us the course syllabus: what a student had to complete to get an A and what a student had to complete for a B. The A was about ten times more work than the B. The B was about five hours of total effort outside the classroom. I was one of the two students in the class who went for the B. So, yeah, I chose a grade other than an A. <^..^>
FWIW, he was furious that "two of the brightest students" didn't care if we got an A or not. Scary, isn't it? This nonsense started over 40 years ago!
