I work in a dept. at a university that does all the proctored exams. None of that technology is allowed in the exam rooms. They have to put their watch, phone, headphones, etc in a locker beforehand. And not only are they being watched individually, the computer is locked down to not allow other applications to open and there are outgoing firewalls in place to block most everything network wise. I’m not saying it’s impossible to cheat, but it’s really really hard.

Some instructors still do in class exams, which would make it easier, but most opted for the proctored type exams especially during Covid.
