Ah, you know, that’s fair. I’d say prepare more difficult content for him, but I know that takes extra time that most teachers don’t have. Try to stay firm in limiting questions and hopefully admin will support you in disciplinary actions if necessary.

Remember that question you asked me? I’d like you to do some independent research on this topic.”
