Thirty-six points, and where they came from
The olympiad sets six problems worth seven points each across two days, so 42 is the maximum. The row published for Iveel Arvis carries five sevens and a one. Problem three, the question that ends the first paper and is set to defeat most of the field, was solved in full; problem six, its counterpart on the second day, yielded a single point of partial credit.
Marks of that shape describe a contestant who was not stopped by difficulty in general, only by the last question in particular. Every figure in the row was fixed in coordination, the process in which the jury and the team leaders agree each script's mark against a published scheme before the table is released.
One of fifteen on the same total
Joint twelfth in 2025 was a crowded place. The official results list Iveel Arvis on 36 alongside Dmitry Grishko, Valentin Glatz of Austria, Ming Yang of Canada, Zhewen Deng and Qiming Xu of China, Yung Ho Kwan and Lincoln Liu of Hong Kong, Eithan Grinzaid of Israel, Lorenzo Degli Atti of Italy, Wooju Ham and Hyeonjun Lee of South Korea, Matej Bachniček of Slovakia, and Andrew Lin and Ruilin Wang of the United States.
That list is a fair picture of how the top of an olympiad table behaves. Fifteen contestants from eleven countries arrived at exactly the same number, and the ranking places them all twelfth because the competition ranks on the total and nothing else.
A field of 630
The 2025 olympiad drew 630 contestants to the Sunshine Coast. Five of them finished on a perfect 42: Ivan Chasovskikh, Warren Bei of Canada, Leyan Deng and Hengye Zhang of China, and Satoshi Kano of Japan. Everyone else in the hall, including the fifteen on 36, was chasing those five.
Mongolia, like every participating country, may send a team of at most six, selected through a national sequence of competitions. A gold medal and a top-fifteen place from a delegation that size is a measurable result for a national programme, and it is recorded in the same table, on the same terms, as the results of much larger mathematical establishments.
What is documented — and what is not
Firm: 36 points of 42, the breakdown of 7, 7, 7, 7, 7, 1, joint twelfth place, a gold medal, Mongolia as the country, and the 2025 olympiad in Australia as the competition. All of it comes from the organisers.
Open: everything else. No age, birth year, school, city or photograph is published in the sources gathered here, and no Mongolian press coverage is among them. Nothing states whether Iveel Arvis competed in other years, or what followed the 2025 competition.

Passer le test de QI →What a single row can carry
Olympiad results are among the few achievements of a teenager that are published by an institution, in full, and left permanently in place. The table gives a score for every problem, which means the result can be examined rather than merely asserted, and it is the same document for a contestant from a small delegation as for one from a country that sends a training squad of hundreds.
It is also the reason a page like this one ends where it does. Gold at the IMO goes to roughly the top twelfth of the field; joint twelfth of 630 is a precise statement of a single summer's work. What came before it and after it, in this case, is not on the public record.
