[^2]\n\nThe Technical Commission for the Review of the 2026-2027 Undergraduate Admission Process concluded that the online exam lacked planning, coordination, and operational validation, resulting in atypical results.

[^4]\n\nThe decision to switch to in-person exams was made after the detection of irregularities and unauthorized use of artificial intelligence in the first fully online exam for the 2026-2027 cycle.
