I heard they do CS exams on air-gapped machines at UC Berkley. Use of AI to do CS homework is strongly discouraged, and if someone cheated, it shows up at the exam...
I guess if I were in school today, I would be accused of using AI on my homework, as I did very well on all of my projects and bombed my tests. My professors all recognized my hard work and gave me good grades, but I feel like that wouldn't go the same way today.
