Ivy League Professor Suspected AI Cheating, Mandated In-Person Final, and Exam Scores Plummeted by 50%

An Ivy League professor at Brown University, Roberto Serrano, suspected his students of using generative AI to cheat on exams. To test his theory, he switched to an in-person final exam, which resulted in a dramatic 50% drop in average scores.

This incident, along with a recent survey showing nearly 30% of Princeton students admitting to AI-related cheating, highlights the extent of academic dishonesty even at elite institutions. The professor has publicly condemned the trend, warning against the erosion of genuine learning.
