A student may challenge the nature, quality, or fairness of an examination or other graded exercise for a particular course, rather than their particular grade on that examination or exercise. Instructors are expected to be scrupulously careful in constructing the exam, choosing grading criteria and applying those criteria, but there is no appeal from a grade on the allegation either that the grader misapplied the criteria for grading the exam, or that the criteria were themselves ill-chosen.
