National Autonomous University of Mexico cancels 3,000 admission exams after AI system flags possible fraud

The National Autonomous University of Mexico (UNAM) has canceled approximately 3,000 admission exams following the detection of an unusually high number of perfect scores by an artificial intelligence system, indicating potential fraud. This marks the first instance of UNAM utilizing an online monitoring system for its admission process, leading to widespread confusion and uncertainty among tens of thousands of candidates. The university observed a significant increase in both perfect and very low scores, prompting suspicions. Mexico's president, Claudia Sheinbaum, has suggested the involvement of the attorney general in the investigation. UNAM plans to organize a new physical exam for approximately 58,000 candidates, with dates and locations yet to be announced. The investigation has confirmed fraud, including the use of mobile phones and external aids.
