yeah it is interesting. when I was at Stanford I was a TA and we just had to leave the room during exams after passing them out and come back at the end to collect the exams. just as I was graduating they started doing the pilot for proctoring exams and I remember students were really upset about it, though my fellow TAs were mostly in agreement that it was a good idea.

side note is that it’s kind of funny because sometimes the seating would be auditorium style so you could easily see papers in front of you if you were higher up… probably difficult to avoid accidentally glancing at someone else’s paper while taking a break, lol.
