<p>For an exam in which the professor gives a take-home exam (closed-book) and a maximum time limit to complete the exam, how would you ever possibly prove that cheating occurred (i.e. the student referred to the book or took too long)? To me, this seems like giving a student WAY too much temptation to cheat. Cheating of this type must occur, and it punishes the honest students. How many violations of this type are ever punished by the Board of Control?</p>
