Accused of cheating on MC exam because I crammed keywords

That is what I plan to do. Its really not my fault that they chose to reuse the exact same exam when deferred exams are supposed to be entirely different from the original exam. I’m not trying to play semantics, but I genuinely dont see why it would be fair to punish me the way a student who brings in a phone or class notes will be punished. I believe I got lucky because they let me, and they knew that I had spent a reasonable amount of time with the questions to be able to do what I did.
