Suspecting AI cheating, Ivy League prof ordered an in-person final; scores fell 50%

After suspecting widespread use of generative AI on take-home midterms, a university professor transitioned their final exam to an in-person, proctored format. The subsequent assessment revealed that student performance plummeted by 50 percent, with only two individuals achieving scores comparable to their earlier results. This discrepancy highlights the growing challenge educators face in validating student proficiency as AI tools become increasingly accessible for unsupervised coursework.
