That is so clever and enterprising. Though it does seem like a lot of work, and you still risk being caught.

My cheating method was foolproof and completely undetectable. See, in the days leading up to the exam, I would look up the answers in the textbook the teacher foolishly provided us at the beginning of the semester. If the answers weren’t there, they’d be in the secret notes I had taken while the teacher was yapping in class days before, clueless they were basically telling us everything that would be on the exam later lol. All I had to do was read those notes the night before, then I could walk in empty-handed and take the exam with no one the wiser that I already knew all the answers!
