@GeekinKorea It’s been enough of a discouragement that nobody’s tried to cheat yet, at least. But I’ve been requiring students to show their work in a process for years. It’s easy in writing courses… harder to apply in other areas, I guess. @GeekinKorea I have used random topic generation in exams, mind—actually bought d8s or d10s to class and had them roll on three tables of topics and then take their pick.
