Two stories: A friend of mine had an extremely small class, 12 students at most in college. A guy in the class came to the last group study session with "I have a plan to cheat on this test." Long story short, they had someone call the teacher and run a short errand within the building. While she was gone, they very quickly shared which part of the test they had assigned. Everyone made an A or B+, but they purposefully got questions wrong here or there based on who needed a higher grade.

2nd, the same buddy (not me I swear) had to download this online proctor software that not only blocks you from opening apps or starting new functions, but records sounds, open processes, and video. I'm not a tech genius like he is, but they went so far as to moniter everything his laptop was doing. It was so invasive, he had to disable Microsoft's firewalls. He also had to film the entire room and not look away from the screen too much.
