Anti-Cheating Spell

Hermione: "And what may I ask do you plan to do if this comes up in the final exam?"

Ron: "Copy off you?"

Hermione: "No, you won't. Besides, according to Professor McGonagall, we're to be given special quills bewitched with an anti-cheating spell."

Ron: "That's insulting! It's as if they don't trust us!"

An Anti-Cheating Spell^[2] was a charm^[1] that prevented a person from cheating.
