In grad school, I got a C+ in one required course. The program gave me credit for the class anyway and awarded me my master's degree. I am now concerned that this was a mistake and my degree could be revoked.
I recently asked the chair about this and she pointed me to the policy (via the Graduate Bulletin), which states that up to three Cs are allowed (I only have the one). But I think she might be incorrect about this; I am not sure whether there is a policy that states grades below a B- could not count towards a degree in a separate policy (like admission to candidacy).
If it turns out that the chair is wrong, could my degree be revoked? I'm aware of this canonical question, but it doesn't cover clerical errors.
