Whatever illicit materials brought into such examinations can contain notes, recording devices, communications equipment, or numerous other things. The point is not what it was, the point is that the rules are in place for a reason. Every DAT candidate is expected to have read the rules and is expected to abide by them. This is a simple concept. Now I have proctored exams before, and although I haven't caught anyone cheating, I am aware of students who have gone to extreme lengths... such as 2-point font notes inside water bottles and tiny carvings on the sides of mechanical pencils. Again, the point is not to discuss methods of cheating, as humans under stress come up with numerous ingenious ways to cheat, the point here is that such examinees are required to follow a set of rules which prevent such methods of cheating to take place.
