Specifically, in the specialized subject exam for grade 10 in Vinh Phuc province in 2025 held on June 3, the specialized Math exam had 6 questions, of which Question 6 (1 point) had the following content:

After the exam, many students and teachers thought that part b of this question was wrong, because the hypothesis could not be proven to be correct.

Regarding this, a representative of the Vinh Phuc Department of Education and Training said that after receiving the feedback, on the afternoon of June 3, the Department convened a meeting to work with the leaders of the Exam Council and the Math Specialized Exam Teachers Group to request a report on the feedback on the Math Specialized Exam.

The report shows that Question 6 (1 point) has statement a (0.75 point) correct; statement b (0.25 point) with the content "Prove that 2025 is the CVP number" is incorrect.

The Vinh Phuc Department of Education and Training immediately suspended the tasks related to the 10th grade admission for the 2025-2026 school year for 3 teachers of the Math test-making group to verify and consider responsibility according to regulations.

The Department also established a Math Marking Team consisting of 6 specialized Math teachers from Vinh Phuc High School for the Gifted and 3 key teachers from high schools in the province to study and evaluate exam questions, answers and propose solutions to report to the Department's leaders.

Based on the proposed plan of the Math Specialized Marking Team, with the principle of ensuring maximum benefits for students, the Marking Council agreed on the following handling plan: Keep the scores of the questions the same, but adjust the scores of points a and b of question 6.

Accordingly, the scoring plan for question 6 is as follows: Move 0.25 points from point b to point a. Therefore, if the candidate can do point a, he/she will get a maximum of 1 point (the entire score of question 6). If the candidate cannot do point a; only does point b and proves that "2025 is not a CVP number" then he/she will get 0.25 points.

After agreeing on the above marking plan and receiving approval from the Department of Education and Training, the Specialized Math Marking Team will proceed to mark the candidates' exams.

Mr. Pham Khuong Duy, Deputy Director of the Department of Education and Training of Vinh Phuc, said that the mistake in the specialized Math exam was regrettable.

Regarding individuals related to this error, the Department of Education and Training of Vinh Phuc is assigning specialized departments to research and propose consideration of responsibility according to regulations.

The exam results will be announced later this week.

The entrance exam for grade 10 of Vinh Phuc High School for the Gifted in the 2025-2026 school year took place from June 1-3. The specialized Math exam was for a total of 227 candidates taking the specialized Math and IT classes (including 129 candidates taking the specialized Math exam and 98 candidates taking the IT exam).
