International Mathematical Olympiad 2023 Exam

Six Vietnamese male students completed their first day of the 2023 International Mathematical Olympiad (IMO) with an exam consisting of three questions and a time limit of 4.5 hours.

This year, the International Mathematical Olympiad is taking place in Japan from July 2nd to 13th, with July 8th and 9th being the two main competition days. Approximately 600 students from over 110 countries and territories are participating in this year's competition, the highest number ever.

The Vietnamese delegation consists of six students: Pham Viet Hung (High School for Gifted Students in Natural Sciences , Vietnam National University, Hanoi), Nguyen An Thinh and Nguyen Dinh Kien (Tran Phu High School, Hai Phong), Hoang Tuan Dung (Hanoi University of Education High School), Khuc Dinh Toan (Bac Ninh High School), and Tran Nguyen Thanh Danh (High School for Gifted Students, Vietnam National University, Ho Chi Minh City). They were selected from the 32 students with the highest scores in the 2023 National Mathematics Olympiad. Among them, Pham Viet Hung won a gold medal at last year's IMO.

The first day's exam consists of three problems (also called questions), with a time limit of 4.5 hours. Tomorrow, candidates will take a second exam of similar length and time. Candidates can receive the exam in one of three languages, but must register in advance and be approved by the organizing committee.

Below is the first day of the 2023 International Mathematical Olympiad:

Based on the total score of the two exams, the organizers will rank the winners from highest to lowest. The total number of gold, silver, and bronze medals will not exceed 50% of the total number of participants. A special prize may be awarded to an outstanding contestant with an impressive solution, and this award is not fixed annually.

The International Mathematical Olympiad for high school students has been held annually since 1959. Last year, all six Vietnamese students participating in the IMO won medals, with two students winning each prize. This achievement placed Vietnam 4th out of 104 participating countries.
