Our Grade 10 student Roy K. attended the international organization held in Erzurum between 23-24-25 December 2022 by the ISF (International School Federation) with the participation of only high school students. Our student, who passed all rounds and succeeded to be included in the National Team, will compete in the ISF World Championship on behalf of Hisar School. We congratulate Roy for this important achievement and wish him success in international competitions where he will represent our School.
