I wouldn't accept the test. Even if I was looking to cheat on the test, I wouldn't know the accuracy or source of the old test and could end up wasting my time. I'm not going to rat out my classmate either. I live my life by my moral code and he is welcome to live by his. Like I said before, the numerous levels of testing during airline training have done a pretty good job so far of weeding out the incompetent pilots, so this classmate may or may not end up as one of those. I've worked hard for everything I've accomplished in school, flying, and life, so I'll just continue to do that.

And I agree with what was said about the circumstances over how some of the pilots saw the old test. If a pilot were to have inadvertently seen some material that he shouldn't have seen, there's always the option of going to someone in the training department and letting them know that you saw something you shouldn't have at a study group or whatever, but you don't reveal any names. That wouldn't be my first course of action, but it certainly is better than just ratting everyone else out.
