A team of school students from Ukraine came fourth in the summary ranking at this year's International Mathematical Olympiad, which took place in Romania. All six students claimed medals, winning four gold and two silver.
The team's supervisor was Bohdan Rublyov, the professor of Kyiv National University of Taras Shevchenko. The squad consisted of Ngoc Thai Skhon Ngo, Illya Koval, Fedir Yudin, Roman Saralin, Arseniy Nikolayev and Alina Harbuzova.
The top three included the U.S., Russia and China, which are considered the long-standing winners of the Olympiad.
The 2018 result is Ukraine's best so far. Previously, this country's best was sixth place, which the national team claimed in three tournaments - in 1997, 2007 and 2014.
