Also, at least on the undergrad level, I don’t know anyone (regardless of field) who does a true forced curve distribution.
All of FLG's economics courses were graded thusly:
Final grades will be given on a curve as required by the Georgetown Economics Department. Approximately 25% of the class will receive A/A-, 50% will receive B+/B/B-/C+ and the rest will receive C and lower. The median grade will be a B.
Which isn't a true curve in the sense that C is average, but it sure did put a dent in FLG's GPA.
