I have highly technical graduate and undergraduate degrees (in CS-adjacent field) and a decade of experience doing software development part time, but no direct experience with quantum computing (or much beyond an undergraduate physics class and an intro CS class in terms of directly related study), and consider myself a better-than-average test-taker. I could get 1D, 1E, 1F and 1T by intuition, 1J by actual knowledge, 1P by tautology, and had roughly no shot at the open-ended questions.
That doesn't mean anything about the quality of his courses or exams. Lots of world-class professors phone it in on their teaching responsibilities because they don't care. I had several of them in school - usually more prestigious professors had worse courses.
I can guarantee you that ChatGPT cannot do anything that a quantum computing class prepares you to do, aside from passing this final. That makes it a bad test.
