On February 3, Tokyo's Board of Education announced that there was a mistake in a math question on the entrance exam for Hibiya High School, which was held on February 21. This error was identified after officials from a private tutoring school pointed out that there was more than one correct answer to a function-related question that had been uniquely designed by the school. Consequently, 24 additional candidates were awarded passing scores, each receiving an extra 8 points on their exams.

The issue arose when all 270 candidates who had passed the exam were informed of the results on February 2, only for it to be revealed shortly afterward that the scoring had to be adjusted due to the mistake. The Board of Education expressed deep regret over the incident, emphasizing the importance of a fair and accurate selection process for students' futures. They are now in the process of confirming the enrollment intentions of the 24 additional passers.

This incident shines a light on the pressures associated with entrance examinations in Japan and the critical role of educational institutions in maintaining fairness and accuracy during their assessments. It raises questions about how exam questions are drafted and reviewed, as well as the responsibilities of educational boards in addressing and rectifying errors that could impact students' lives significantly.
