Vietnam ranked 9th out of 113 countries at the 2025 International Mathematical Olympiad

On the morning of July 19, the Ministry of Education and Training received official information on the results of the Vietnamese national team participating in the 66th International Mathematics Olympiad (IMO) in 2025, held in Sunshine Coast city, Queensland state, Australia.

As a result, the Vietnamese team ranked 9th among the participating countries, with 6/6 students winning medals, including: 2 Gold Medals, 3 Silver Medals and 1 Bronze Medal.

Specifically, the Gold Medal winners were Vo Trong Khai, grade 12, Phan Boi Chau High School for the Gifted, Nghe An province; and Tran Minh Hoang, grade 12, Ha Tinh High School for the Gifted, Ha Tinh province.

The three students who won Silver Medals include: Nguyen Dang Dung, grade 12, High School for Gifted Students of Natural Sciences , University of Natural Sciences, Vietnam National University, Hanoi; Nguyen Dinh Tung, grade 11, High School for Gifted Students of Natural Sciences, University of Natural Sciences, Vietnam National University, Hanoi; Le Phan Duc Man, grade 12, Le Hong Phong High School for Gifted Students, Ho Chi Minh City.

In particular, the delegation had an 11th grade female student participating and excellently winning a Bronze Medal, that is Truong Thanh Xuan, Bac Ninh High School for the Gifted, Bac Ninh province.

This year, the Vietnamese delegation included students from the three regions of the North, Central and South. Compared to the results in 2024 (2 Silver Medals, 3 Bronze Medals and 1 Certificate of Merit), the achievements of the Vietnamese delegation in 2025 were clearly superior.

With a total score of 188, the Vietnamese delegation ranked 9th out of 113 countries and territories participating in this year's competition, behind the delegations: China (1), the US (2), South Korea (3), Poland and Japan tied for 4th place, Israel (6), India (7), Singapore (8).

The 66th International Mathematical Olympiad will be held from July 10-20, 2025 in Sunshine Coast, Queensland, Australia, with the participation of more than 639 contestants from 113 delegations representing countries and territories. This is the second time Australia has hosted the IMO, after the first time in 1988.

The total number of medals of this year's Competition includes: 72 Gold Medals, 104 Silver Medals and 145 Bronze Medals.

The IMO 2025 exam consists of 6 problems: 2 arithmetic problems, 2 combinatorial problems, 1 geometry problem and 1 algebra problem (with combinatorial statements and combinatorial thinking requirements). This shows the tendency of this year's exam to focus on combinatorial content.

Notably, the only geometry problem in the exam, problem number 2, was proposed by Vietnam and the author was Mr. Tran Quang Hung, a teacher at the High School for the Gifted in Natural Sciences, University of Natural Sciences, Vietnam National University, Hanoi.

This is the fourth time Vietnam has had a problem selected for the official IMO exam, after 1977 (author: Phan Duc Chinh), 1982 (author: Van Nhu Cuong) and 1987 (author: Nguyen Minh Duc).

The closing ceremony and awards ceremony of the Competition will take place at 4:00 p.m. on July 19, 2025 (local time) in Australia.
