my friend went to an engineering competition this past week during midterms and informed our intermediate mechanics professor late, 2 days prior, so now the professor is penalizing him. he's giving him the exam with 2 extra questions in the same period of time and the maximum he can get is 75%. his sole reason for doing this is that he's insulted that it was such short notice. he's a tenured professor. is there anyway to appeal his decision? can the department chair override his decision. i fear that nothing can be done even though i hope that something can be.
