It is at the discretion of the instructor whether questions by students shall be entertained during exams. However, faculty are discouraged from doing so due to a tendency to reveal too much information during the clarification process, which gives an unfair advantage to the questioning student. Nonetheless, if questions are permitted, then professors should take caution not to be leading or to provide hints when responding to questions. Professors are not allowed to tell students whether their answers are correct or to provide any other clues. If faculty member gives any elaboration or correction of a question to a student, then this same information must be given to ALL students.
