@nberlat You have to see what happens in an environment where cheating isn't something one or two kids do quietly but something the whole class does openly. It become a class management issue. You can try to manage in other ways besides the fear of the exam - personal charisma, making the class more fun, low-stakes testing with retests and corrections, etc - but it does change the class dynamic when you reach that tipping point of the MAJORITY of the class cheating even when they don't have to.
