Allow instructors to include special instructions for exam or blocks of questions (for online or paper exams)
Sometimes students can benefit and understand how to approach exam questions if instructors can give them specific direction that is not part of the actual test question.
"This exam has 20 multiple choice and 10 True/False questions" Select the best answer."
"The following six short-answer questions address the philosophical differences regarding voting rights in 1960 between Richard M. Nixon and John F. Kennedy."
