This reminds me of back at university we had to use a platform called "Wiley Plus" for weekly physics homework.
To prevent copying, while the equations needed remained the same, the numbers (inputs to what you had to work out) varied across user sessions.
One lad in the course wrote a website that he updated weekly that mimicked the UI/UX, you would plug in the values WP gave you and it would emit an answer.
The following year I took over maintaining it, and ended up in a spot of bother with the administration.
There was also another homework website that some lectures made us use, which did all the shit client side in JS. You could just inspect element and get the answer.
I honestly still don't get the point of those additional homeworks, on top of assignment and lab report workloads at university. They seemed to only exist to loosely tick a box regarding "continuous assessment".
Relatedly, they also implemented 5% credit for attendance by proxy by making us rent these radio " clickers" from the university, each with a unique ID tied to a student.
During lectures, there would be multiple choice questions asked, where the answer was irrelevant - it was a means of counting attendance.
Naturally by the second month people were delegating their clicker to someone else if they needed to skip a class.
A couple of years later, smartphone apps replaced the clickers, and SDR became affordable, granting the university a near-miss from any radio shenanigans.
