I guess you would have your y axis be “price” in terms of amount of time studying in this case.  In that case, the demand curve would be vertical — at any price, the student only wants one outcome — an A.For any other outcome, his quantity demanded would be zero.I suppose the most likely reason why this is not realistic is that no one really wants an A so badly as to spend literally all of their time studying for that one particular class.  There would surely come a point when the student decided that the marginal return on his studying was no longer worth the marginal cost.
