Version 7.7.3
The statistics don't lie: students scoring above 100 jumped from 3% to 16% in a single year. Software was sold openly on TikTok that would sit the exam for you. A university that let those results stand would be handing places in medicine and law to people who bought their way in. Lomelí's decision to self-correct is exactly what accountability looks like.
UNAM chose to move online for the first time in its history, contracted a company whose AI monitoring was trivially defeated, then forced 58,000 students — including those who scored legitimately — to resit in person with no guarantee their original results would be honored. Honest students are paying the price for an institutional gamble that failed spectacularly.
