There was no AI policy in his class, so you could use it for whatever (except for exams, obviously). His lectures are fully on a chalkboard and recorded. The homeworks always took me at least 6 hours to complete. Some of them were questions that he wrote, some of them were ZyBook problems. The exams were hard. Four questions that were split into smaller questions. The exams are 120 points, but a 100/120 is a perfect score. The average for our final was a 53%.
