Exams are a good method for learning but they are not a good way to test and assess knowledge. This is because they cause unnecessary stress, so if it was unto me I would let people do exams to learn the material but I wouldn't give them a test to ultimately judge their ability. Google notebook llm is surprisingly good at generating multiple choice questions. The podcasts are okay too as long as you keep them medium to short. The exams also might be better when they are short as well. When I say 'better' I mean better at learning rather than 'testing as much knowledge as possible.'
