An AI-supervised remote exam went so badly that 58,000 students must retake it

UNAM, Mexico’s largest university, will require 58,000 applicants to retake an entrance exam after its first fully remote administration—using a lockdown browser and AI-powered webcam proctoring—produced results unlike previous years. The share of test takers scoring at least 100 out of 120 rose from 3.5% between 2021 and 2025 to 16.3% this year, a roughly fivefold increase. The outcome has called the reliability of the AI-supervised exam into question and disrupted admissions for thousands of students.
