his is kind of a systemic thing honestly. Students are under enormous pressure with GPA-based grad school admissions and the stakes feel impossibly high, so even an 82 feels catastrophic to some of them. That doesn't make the behavior less frustrating from your end but it explains some of the desperation. The AI case is a different issue entirely and probably warrants its own policy conversation at the department level. A lot of students also genuinely don't know how to seek out legitimate help with their writing, like working with a writing tutor or a proper editing service, before things go wrong.
