Ivy League Professor Suspects AI Cheating, Orders In-Person Final; Scores Drop 50%

A Brown University economics professor, Roberto Serrano, suspected widespread AI cheating in his class and mandated an in-person final exam, resulting in a 50% decline in scores. This incident highlights the prevalence of generative AI misuse among elite students, who are often ambitious and overscheduled.

A separate survey of Princeton students found that 29.9% admitted to using AI to cheat on exams or assignments. The dramatic score drop suggests that many students had been relying on AI rather than mastering the course material.
