It is very difficult for them to prove the allegation of AI cheating. If you didn't cheat, you should fight. You have legal rights, and you don't have to roll over. I represent students who have been unfairly accused of AI cheating. Properly defended, it is not that easy for the school to win.

I have found the whole honor system of academics to be just another stick to whip students with when convenient. I am not opposed to any sort of honor system or academic integrity when there is actual honor and integrity, but the system needs to apply to both sides. None of this "rules for thee, but not for me."
