Maybe, maybe not. At Virginia Tech, at least, every professor was required to keep all their previous tests and exams on file at the library. It was a goldmine of a resource when you were studying for finals.
Even without a system like that, profs often share their finals when multiple professors teach the same class. It's just professional courtesy.
I guess I'm just not making my self clear. I'm talking about the memo, NOT THE TEST. When I went to school, all the old tests were on file at the library too. The memo is something specific to the tests the students turned in, or so it seems to me. Memos like this one were NOT ON FILE any place where I knew about.
