This case in Canada was between students who were complaining about a professor and the school who claimed doing so was misconduct. The school lost because the punishment infringed on students' freedom of speech.

By this logic, does freedom of speech protect students from punishment if they were to release details of a test question while complaining about it in a similar manner? What legal right do universities have to mandate confidentiality of such things? (I hope this doesn't sound facetious)
