" IIRC, our semester grade was calculated based on two pre-lims & one final exam. Nothing else."
My recollection is no doubt worse than yours, but I think in my class we also had graded assignments in recitation, a general recitation grade, and a term paper. Depended on the professor I guess, as always.
Those classes served me well, years later I placed out of the economics sequence in my MBA program by re-reading Samuelson.
No clickers though, in those days.
