Many Vietnamese students have failed to graduate this year despite achieving high scores in certain subjects. The failures stem from receiving failing grades—a "zero"—in other required subjects. Specifically, cases have emerged of students scoring highly in mathematics, even achieving a nine out of ten, but failing literature with a score of just one. This disparity in performance has resulted in these students being ineligible for university admission this year. The situation highlights the importance of balanced academic performance across all subjects in the Vietnamese education system. Authorities are likely to review the implications of this issue for future exam regulations and student support. These instances underscore the rigid requirements for graduation, where proficiency in all subjects is mandatory.
