A top Mexican university used AI to prevent exam cheating. Now thousands of admissions are in doubt

UNAM annulled thousands of tests after results showed an unusually high number of perfect scores, suggesting some students cheated either through using artificial intelligence tools or by obtaining the questions in advance.

Entrance exams for the various programs at the National Autonomous University of Mexico, which students took remotely for the first time, produced scores much higher than in previous years, raising suspicions about the use of artificial intelligence assistance.
