Mexico’s largest and most prestigious university has announced that about 58,000 students will have to resit their entrance exam after abnormally high test results raised suspicions of widespread cheating. Nearly 160,000 students took the entrance exam earlier this summer. Hundreds of Unam applicants protested in Mexico City on Monday against having to take the control exam, blocking major thoroughfares in the south of the capital. The drive for more equitable access led the university to offer the exam online for the first time this year. The Unam announced in July that it had filed a criminal complaint after detecting the alleged irregularities.
