A tie at the summit
The official scoreboard of EGMO 2023, held in Portorož, Slovenia, lists Nogah Friedman of Israel on 42 points out of 42 with a gold medal. Thirteen other contestants matched the total, which means the competition produced no outright individual winner on score alone.
The fourteen included all four members of the Chinese team — Shuwen Hu, Lai Yuan, Sihan Su and Yiran Qiu — together with Fidan Garayeva of Azerbaijan, Maria Drencheva of Bulgaria, Polina Henyk of Ukraine, Isabella Zhu and Vivian Loh of the United States, Xiangyue Nan of Australia and two Turkish contestants, Melek Güngör and İrem Gülce Yazgan.
What 42 points requires
The paper sets six problems and marks each out of seven. The problems are not calculations with answers to be checked but propositions to be proved, and the marks follow the completeness of the argument rather than the correctness of a final line.
Marking is done by coordination between the examiners and the team leaders, solution by solution. A score of 42 means that six written proofs were read closely by people looking for gaps and that none were found. It is the hardest possible result to argue with.
The rest of the table
Below the perfect scores the 2023 scoreboard falls away quickly, through gold, silver and bronze medals to honourable mentions, awarded on bands of score rather than fixed positions. Roughly fifty countries took part, most with teams of four, giving a field of about two hundred.
The following year the picture was completely different: at EGMO 2024 in Tskaltubo, Georgia, the highest score in the world was 41, by Hannah Fox of the United States, and nobody reached 42. The contrast is the clearest available measure of how much the difficulty of a single paper can move the results.
Israel at the olympiad
Friedman's row on the scoreboard carries a seven in every problem column, next to the Israeli flag. National teams at EGMO are chosen through domestic selection, so a place on the team is itself the outcome of a competition, and a perfect paper at the olympiad puts a contestant at the front of everyone who came through that process worldwide.
The scoreboard adds no commentary, no team totals beyond the arithmetic and no profiles. It is a record of what was written on the day, which is both its limitation and the reason it can be relied on.

Passer le test de QI →What is documented — and what is not
The firm facts are the score of 42 out of 42, the gold medal, the country, the year and the host city, all from the olympiad's official scoreboard, and the count of fourteen perfect papers in the same table.
Everything else is absent. No age, date of birth, school or home town appears in the source, no photograph, no interview and no report of any later result. Whether Friedman has competed at other olympiads, in Israel or internationally, is not documented in the sources gathered here.
