I think there's more than one cultural difference at work here. It's not just that there are cultural differences between the U.S. and China, but that there are generational cultural differences between you and me. It's been almost 20 years since I was an undergraduate. Back then, at my institution anyhow, sharing old exams that weren't publicly posted was considered deeply dishonest. As bad as having a ringer sit the exam for you. I was deeply shocked when, as a senior, I finally learned about the fraternities' libraries. Certainly, I was naive at the time. But my point is that, however you want to rationalize the practice of sharing old exams, it gives an unfair leg up to people who have access. At any rate, I thank you for the discussion. I'm going to be away from the internet for the weekend, so I'll yield the floor and read any further responses later.
