On the morning of July 19, 2025, the Ministry of Education and Training (MOET) received official information about the results of the Vietnam national team's participation in the 66th International Mathematical Olympiad (IMO) in 2025, held in Sunshine Coast, Australia.
As a result, the Vietnam team ranked 9th among the participating countries, with 6/6 students winning medals, including: 2 Gold medals, 3 Silver medals and 1 Bronze medal.
The two students who won the Gold Medal were Vo Trong Khai (class 12, Phan Boi Chau High School for the Gifted, Nghe An) and Tran Minh Hoang (class 12, Ha Tinh High School for the Gifted). Khai Dat has 38/42 points, in the top 10 most excellent contestants, while Hoang has 35 points, ranked 27th. The two male students were classmates in high school in Ha Tinh.
The three Silver Medals went to Nguyen Dang Dung (class 12, High School for the Gifted, Hanoi National University) with 34 points; Nguyen Dinh Tung (class 11, High School for the Gifted) - 31 points, and Le Phan Duc Man (class 12, Le Hong Phong High School for the Gifted, Ho Chi Minh City) - 28 points.
The only female student in the group, Truong Thanh Xuan (grade 11, Bac Ninh High School for the Gifted) won the Bronze medal with 22 points.
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), Korea (2), Poland and Japan, ranked 4th, Israel (6), India (7), Singapore (8).
This year, the achievements of the Vietnamese delegation in 2025 have clearly outperformed, increasing by more than 20 places compared to last year (in 2024, Vietnam had two Silver medals, three Bronze medals and one certificate of merit, ranking 33rd - the lowest in 50 years of participating in IMO).
The 66th International Mathematical Competition will be held from July 10 to 20, 2025 in Sunshine Coast, Australia, with the participation of more than 639 contestants from 113 delegations representing countries and territories.
This is the second time Australia has hosted IMO, after the first time in 1988.
The IMO 2025 exam consists of 6 problems: 2 sets of numbers, 2 combinations, 1 toan problem and 1 continued problem (for combined speech and requirements for combined thinking). This shows the trend of this year's exam questions leaning towards combined content.
Notably, the only toanistic problem in the exam is problem No. 2, proposed by Vietnam and authored by 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 the problem selected for the official IMO exam, after 1977 (author: Phan Duc Chinh), 1982 (author: Van Nhu Cuong) and 1987 (author: Nguyen Minh Duc).
