TEHRAN – Iran grabbed two gold medals, three silver medals, and a bronze medal at the 66th International Mathematical Olympiad (IMO 2025), held from July 10-20 in Australia.

Hosted by the Australian Maths Trust, the event attracted more than 600 high school students from 112 countries.

The competition represents the culmination of many years of mathematical endeavour and hundreds of attempts at solving problems.

Bardia Khosh-Eqbal and Mehdi Aqajanloo grabbed gold medals, Mohammad-Reza Attaranzadeh, Mohammad-Sajad Memari, and Amir-Hossein Zarei secured silver medals, while Parsa Tajallaei won a bronze.

The IMO is the largest and most prestigious of all the international Olympiads, having grown from seven countries to over a hundred each year. IMO brings the brightest young minds from around the world and represents the culmination of many years of mathematical endeavour and hundreds of attempts at solving problems. Australia has participated since 1981 and has hosted only once before (Canberra, 1988).

The team had ranked second in the 3rd International Mathematics Summer Camp (IMSC) held in Beijing, China, from June 20 to July 12, 2025.

Bardia Khosh-Eqbal grabbed a gold medal, Mehdi Aqajanloo, Parsa Tajallaei, Mohammad-Reza Attaranzadeh, and Mohammad-Sajad Memari won silver medals, and Amir-Hossein Zarei won a bronze medal, IRIB reported.

It was a three-week training program designed to strengthen students’ problem-solving skills in elementary mathematical fields, including algebra, geometry, number theory, combinatorics, and to enrich their analytic thinking, fostering a passion for math.  

IMSC 2025 brought together over 300 people, including students and lecturers, from 32 countries such as Belarus, Belgium, Cameroon, Germany, Iran, Kazakhstan, Kyrgyzstan, Turkmenistan, the United States, Romania, Poland, and Uzbekistan.

The 65th IMO was held from July 11 to 22, 2024, in Bath, United Kingdom. Some 108 countries and 609 students competed. The Iranian team scored 137 points, earning 19th place.
