Since Professor Goodheart counts only the best midterm grade, Nancy would be indifferent between any two scores where the highest score is the same (in this case, 30), which explains why the indifference curve has a slope of zero at the point (20, 30). This would not apply to Professor Stern's class, where the worst score matters.
