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

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

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

Specifically, the outstanding Gold Medal winners were Vo Trong Khai, a 12th-grade student from Phan Boi Chau Specialized High School in Nghe An province; and Tran Minh Hoang, a 12th-grade student from Ha Tinh Specialized High School in 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.

Notably, the team included an 11th-grade female student who excelled and won a Bronze Medal: Truong Thanh Xuan from Bac Ninh Specialized High School, Bac Ninh province.

This year, the Vietnamese delegation includes students from all three regions: North, Central, and South. Compared to the results of 2024 (2 Silver Medals, 3 Bronze Medals, and 1 Certificate of Merit), the achievements of the Vietnamese delegation in 2025 have shown a clear improvement.

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

The 66th International Mathematical Olympiad (IMO) will be held from July 10-20, 2025 in Sunshine Coast, Queensland, Australia, with the participation of over 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 in 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 authored by Mr. Tran Quang Hung, a teacher at the High School for Gifted Students in Natural Sciences, Faculty of Natural Sciences, Vietnam National University, Hanoi.

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

The closing ceremony and awards presentation for the competition will take place at 4 PM on July 19, 2025 (local time) in Australia.
