Some more info about ProctorU (for others who haven't heard about it):

> Rather than one proctor sitting at the head of a physical classroom and roaming the aisles every once in a while, remote proctors peer into a student's home, seize control of her computer, and stare at her face for the duration of a test, reading her body language for signs of impropriety.
That article is from 2013, I wonder how much of this is now partially automated (i.e. relying on human remote proctors)?
