The Mathematical Grammar School Cup, an international competition held annually every June in Belgrade, aims to encourage the development of mathematics, physics, and informatics knowledge among all participating students. In 2024, we continued our tradition of sponsoring the event by providing all contestants with competition-branded equipment, including t-shirts, rucksacks, and stationery. At the closing ceremony, held at the National Assembly building of the Republic of Serbia, Click for Serbia provided gifts to all domestic and international medallists, presenting them with A Brief History of Belgrade, a book available in four languages, created in collaboration with Slavenko Terzić, PhD.
