Brown University economics professor Roberto Serrano says he became suspicious after students in one of his classes earned unusually high scores on a take-home midterm exam. The class average reached 96%, far above the course's typical range of 65% to 80%, prompting him to take a closer look at the submissions.

According to Serrano, many of the answers shared similar characteristics that he believed were consistent with AI-generated work. Although he could not conclusively prove students had used artificial intelligence, the similarities were enough for him to change the format of the final exam.

Instead of another take-home assessment, Serrano required students to complete the final exam offline and in person. The results were dramatically different. The average score dropped to 48.6%, 18 students withdrew from the course, nine did not take the final exam, and 19 students failed.

Serrano said the experience highlights the growing challenge universities face as AI tools become more widely available. He argues that colleges need to rethink how they assess student learning and develop clearer policies to address AI-assisted cheating while maintaining academic integrity.
