My architectural exams are proctored/monitored. To get in I have to schedule the test, show up on time, provide ID, leave all personal effects in a locker. Get photo ID'd, have my photo taken, finger print taken (not during covid), searched (metal detector only now, used to come with a pat down too) sign in, given paper and pen, taken directly to the computer station, enclosed on three sides, with a camera directly behind, and several more in the room. Me leaving the chair has to be approved, and they randomly patrol the tests, literally looking over your shoulder some times.
And there are still cases of cheating. Considering that even requiring a voter ID is racist, no reasonable person could argue there isnt plenty of cheating going on. It's just impossible, because of the lack of checks, to prove any of it. And that's how the parties want it
