[aephi alum]

I don't see a problem with collecting old exam information, as long as it's not against the university's honor code.

It was very common at my school for students to make "bibles" - a collection of lecture notes, problem sets and answers, exams and answers, and any other potentially useful information. Many groups, including GLOs and dorms, kept libraries of bibles donated by members. Greeks didn't have a particular "advantage" over non-greeks, because groups other than GLOs did keep bibles, and study groups tended to form along the lines of who was in your major rather than who was in your GLO.

For the most part, the professors with whom I studied created new exam questions each semester, so the bibles were useful for practice but not for rote memorization... which is how it should be. Exams should measure how well you have absorbed the material, not how well you can regurgitate information.
