You’re giving me flashbacks to this Unix class I had in junior year. The professor had (either prepared or stolen) a 100 slide deck, and as you said the final was based solely on the slides.

Well I did attend just to have him read the slides in broken English. (No shade on non-native English speakers btw, but if you’re teaching native English speakers you kind of have to put in the effort, and this guy was coasting on straight phonics as he read these slides and couldn’t answer any questions not covered by his slides.)

Then I converted the slides into a TTS audio file, snaked an earbud up my sleeve, took and passed the test.
