A few years ago, I did a module where everyone failed. We had to go back and do the course again.

At the first re-take class, I told the course lead that we needed him to stick to the course spec and teach the content that was going to be examined instead of talking about a different research topic each week that didn't come up in the exam. Or failing that to give us a list of readings that would do the same job.

He was very confused. Giving us a tour of the limits of the field was the greatest value he could give us as an active researcher. But we needed to graduate and the class was a compulsory requirement. Over the next few weeks he stuck to the syllabus but kept making comments about students who didn't care about the subject and were just in it for the money while looking at me. Empathy isn't a requirement for success in STEM research I guess.
