Before the pandemic, two of my coworkers were first year law students together at the local university. The teachers discovered a cheating ring of 170+ students in their class of something like 200 students.
They just made them take a new version of the most recent exam and there was no other punishment, because it was too devastatingly large a portion of their students to expel them all, even though that was their stated policy.
I suspect something similar will happen with AI, and it will be just as disappointing.
