Brown University Professor's In-Person Exam Reveals Widespread AI Cheating as Scores Plunge 50%

An Ivy League professor at Brown University, Roberto Serrano, suspected his students were using generative AI to cheat on exams. After ordering an in-person final, scores fell by 50%, indicating many students had relied on AI rather than learning the material. This incident reflects a broader trend: a survey of Princeton students found that nearly 30% admitted to using AI on at least one exam or assignment, suggesting widespread cheating even at elite schools.
