<p>again, barboza, professors may engage in a variety of habits or practices but without the actual presumption that old test questions=new test questions (a presumption that cannot be made even by a student using the old test) I don’t see how that is cheating per se. A simple fix would be for professors to tell students directly “I expect you not to use old tests”. Some may shy away from giving that injunction because they don’t want to admit openly that they never change their tests, I don’t know. But, as tiredofsnow’s post above suggests, many professors over the years have NOT considered this as cheating- as he says, the engineering library itself carried files of old tests! And I have heard some teachers actually challenge students to use old tests (as if to say, “you’ll be sorry if you rely just on that”), and left it at that.</p>
