Thirty-eight out of forty-two
The EGMO 2024 scoreboard, published by the olympiad itself, records Cloris Xu of Australia on 38 points out of a possible 42, ranked joint second overall and awarded a gold medal. The same total and the same rank belong to Aino Aulanko of Finland.
Above them sits one name. Hannah Fox of the United States finished first with 41 points, a single problem short of a perfect paper. The gap between first and joint second is three marks, which at this level can mean one incomplete case in one proof out of six.
What the olympiad asks
EGMO sets six problems and marks each out of seven, giving a maximum of 42. The problems are proofs, not calculations: a contestant who reaches the right answer without justifying it earns little, and a contestant who builds a complete argument for a harder problem can outscore several partial attempts elsewhere.
The scoreboard shows the pattern clearly. Full marks of seven appear repeatedly against individual problems across many countries, while totals near the ceiling are rare. Consistency across all six is what separates the top of the table, and it is why a score of 38 is closer to the summit than the arithmetic alone suggests.
An Australian at a European olympiad
The competition is named for Europe but the scoreboard is not confined to it. Teams from outside the continent appear on the 2024 table, Australia and the United States among them, and in 2024 the two highest individual scores in the world belonged to competitors from the United States and Australia respectively.
That makes Xu's result a double achievement: a gold medal, and a gold medal won by a guest team against the strongest national squads in European mathematics. The scoreboard as read here lists roughly fifty participating countries, most fielding teams of four, which places her result inside a field of around two hundred contestants.
What a gold medal at EGMO signifies
Olympiad medals are awarded on a sliding scale rather than to a fixed number of winners, with gold reserved for the highest band of scores. Reaching that band requires solving problems that have been written specifically to defeat the best school-age mathematicians in the world, under examination conditions, with no reference material.
Every contestant in Tskaltubo had already won a national selection to be in the room. The scoreboard records what happened after that: a small group at the top, a long tail of partial credit beneath it, and two names sharing second place with 38 points apiece.
What is documented — and what is not
The firm facts come from the olympiad's own scoreboard: the score of 38 out of 42, the joint second placing, the gold medal, the year, the host city of Tskaltubo in Georgia, and the identity of the contestant who finished above her. Competition results published by the competition are the strongest evidence this kind of record can have.
Nothing personal is attached. No date of birth, age, school, city or photograph appears in the source, and no interview or follow-up has been published in the sources gathered here. Whether she competed at other olympiads, before or since, is not recorded on this page, and the exact number of participating countries is stated only approximately in the scoreboard as read.
