Well, after an hour of trying to get MS Teams to work, since they unexpectedly just gave up for the day, he basically went "Fuck it, tests cancelled, we'll just have big ones at the end of the semester, we're done for today, bye." The teachers themselves are just as fucked as we are, problem is the tech not holding up (uni network breaking under the stress in the first week resulting in near-complete communications breakdown, MS Teams working about as well as anything from Microsoft) and the dean being an idiot.
