This is a fast-moving situation, obviously, but I think eventually the role of education is going to be in preparing students to use AI effectively in their field, and not in trying to teach (and test) in the world pre-AI.
But until we get there, I think it is going to be challenging.
RE: the Physics 50’s. My freshman year, the mean on the first midterm for Physics 53 (or whatever the E&M course was) was a 34. There were students who got a 0 (literally not even partial credit on any of the questions). So, when I took it as a sophomore, I don’t think I’ve ever studied as hard for a class. Unbenknownst to me, in response to the grading the year before, the test was made substantially more accessible, and so Physics 53 was my best grade at Stanford.

re: calculators, it was, the discussion then (for me 1978-82 and before that in high school) was around affordability as they were not cheap and not all students had them so was it a competitive advantage to let some students use them, and yes in high school it was four function calculators......in my sophomore year our RA had interned at HP and got a bunch of us a deal on the HP34c which was a great deal at the time. The hard core EEs ponied up for the HP41c which had more capabilities
in one of my chemical engineering classes the mean for the midterm was 18 and the mode was zero.....and we all ended up passing, I got a C+ in the class which ended up being the 8th highest grade out of ~30 people and was grateful....a couple of years earlier that prof had failed ~33% of the class in a senior year required class, he was persuaded to regrade the exams or have to teach the class again the next quarter....
In Serra (now Sally Ride) my sophomore year one friend had a terminal in his room that he used for dial-in access to LOTS avoiding queuing up to get access to the terminals there. Of course it was also used for a space attack game (not sure of the name but it was like space invaders) and one of the issues would be you could be attacked and lose your weapons targeting capability, well one guy in the dorm (he of the physics 60 series and degree in physics) would bark out polar coordinates for aiming the weapons, and he was always correct....he was also the handstand pushup champion of the dorm....
in another interesting exam story in one of my physical chemistry classes the prof gave the exact same midterm as the year before, his reasoning was that our year the class sessions were longer (my vague recollection is our classes were 75 min twice per week vs 50 min three times per week the year before) and he wanted to see the impact of longer time on how well students did, well some (not me) had access to the previous exam and did really well giving a bimodal distribution to the test scores......he did not repeat this experiment (at least that year)....
