<p>Certainly, looking at old tests is not considered directly cheating – but you gain advantage if the questions reappear or are similar in nature, and therefore this becomes a form of cheating. If professors prohibited students from studying old tests, it is clear that they would be recycling questions in the exam, which would only encourage more students to seek these old tests. And who has the advantage? I would say Greek organizations for sure. Plus, no professor in UVA to my knowledge has put old tests on file in libraries. He/she would give them out to the entire class for practice or put them up on toolkit.</p>
