When a user asks questions from old exams in preparation for an upcoming exam should we apply the "homework" tag, even if the old exams aren't necessarily assigned for a grade? I'm ambivalent; it's not really homework per se, but part of the value of the homework tag (to me) is as a flag that a good response might lead to the correct answer instead of giving it, or include more detail on the initial steps of a solution, etc.
(Prompted by this question, which has other problems besides...)
