UNAM orders 58,000 students to retake entrance exam after cheating concerns

UNAM will hold a second, in-person entrance exam for about 58,000 students after investigators flagged irregular results in a largely online test monitored by AI; nearly 160,000 applicants took the test, authorities annulled around 3,174 results amid concerns of identity impersonation, external help and cheating, prompting protests and a criminal complaint as admissions are paused and the new academic year is pushed back to August 31.
