Professor Stickler always grades "on the curve." "Yes, I see to it that my grades are distributed as 7 percent A's, 24 percent B's, 38 percent C's, 24 percent D's, and 7 percent flunks," he explained to a young colleague.
The colleague, convinced that the professor is really a softer touch than he sounds, looked at Professor Stickler's grade distribution for the past year.
