Romania’s team ranked first place at the 29th edition of the Junior Balkan Mathematical Olympiad (JBMO), held June 24 – 19 June, 2025, in North Macedonia (Struga and Orhid).
With a total of 208 points, the six students from the national team earned four gold medals, three of which were with perfect scores, and two silver medals, as follows:
Gold medals with perfect scores:
Andrei Nemțișor (7th grade, “Costache Negruzzi” National College, Iași)
Mihai-Alexandru Ardelean (8th grade, Gymnasium School No. 11, Oradea)
Ștefania-Teodora Mihăilescu (7th grade, International Computer Science High School, Bucharest)
Gold medal:
Ilinca-Rucsandra Radu (8th grade, National College Iași)
Silver medals:
Tudor Chelaru (8th grade, “Emil Racoviță” National College, Iași)
Alexandru Ghenea (8th grade, “Grigore Moisil” National College, Bucharest)
The Romanian team was led by professors Marius Perianu (“Ion Minulescu” National College, Slatina) – leader, and Cristian-Teodor Mangra (“Tudor Vianu” National College, Bucharest) – deputy leader. With support from the Romanian Mathematical Sciences Society, Professor Marius Vlădoiu, PhD, from the Faculty of Mathematics and Computer Science at the University of Bucharest, accompanied the Romanian delegation as Observer A.
The JBMO includes teams of 6 students each from Albania, Bosnia and Herzegovina, Bulgaria, Cyprus, Greece, North Macedonia, Moldova, Montenegro, Romania, Serbia, and Turkey – official member countries of the competition – as well as teams from Armenia, Saudi Arabia, Azerbaijan, Croatia, France, Georgia, Kazakhstan, Kyrgyzstan, Malaysia, Turkmenistan, Ukraine, and Uzbekistan – invited countries. As the host country, North Macedonia was allowed to participate with an additional team (North Macedonia B), with invited status.
Last year, Romanian students earned five silver medals and one gold medal at the Junior Balkan Mathematical Olympiad (JBMO) held in Turkey. At the end of April this year, Romania also ranked first at the 2025 Balkan Mathematical Olympiad, with four gold medals and two silver medals. The team’s coordinator, Dean of the Faculty of Mathematics and Computer Science at the University of Bucharest, Professor Cătălin Gherghe, PhD, stated at that time: “Everyone agreed that this year’s problems were more difficult than in previous years. Nevertheless, all our students scored full points on the first three problems, a rare achievement.”
