Look, I was a pretty crappy student in a lot of ways. But this thread has a few instances of folks implying that, especially at more "elite" schools, blatant cheating is practically routine and everyone does it. Again, I was not a model student, but it's pretty maddening to hear that. I didn't cheat to get my degree. I'd ask that you all not rationalize your cheating to the point of making your successors feel comfortable doing so, or worse, feel like outcasts for not doing so.
I don't think anyone has denied the existence of students who don't cheat. If 80% of a class cheats, that means 20% don't. You may have been among those.
