As a TA, I've seen graduate students succeed with answers blatantly copied from the internet (i.e. screenshots of the answer, rote copied answers, etc), and then I was asked to make a calculation to make sure the points reduction would not impact their final grade.
This was before generative AI became so commonplace, and I got the impression this is super common place. It was a really disillusioning moment for me.
Seeing my fellow grad students cheat, then brag in the public student lounge to multiple people about having the highest score on the exam by “oh I didn’t even understand that question I just copied the answer key and I still got the highest score”, broke something in me.
Our institutions are failing us, and I have never been more disillusioned.
