Despite all that, I still 'passed' and even got a B for my 3D work because that's what I was actually interested in ( The fucking cretins ) despite it being advertised as a 'games design' course we did not look at a single game engine or line of code and 3D modelling was barely taught. They were more interested in prepping people for university.

That's exactly right. Literally no one in that class knew anything about game design, 3D modeling, or anything else. They just new that it could be a safe, easy, course to teach and the kids wouldn't know anything about the topic to challenge it, and so long as they did University prep, it was close enough.
