Our 3rd-year IT students, Luka Sudarević and Dušan Stanić, who were once students of the IT department at the "Svetozar Marković" Gymnasium themselves, returned to their former classrooms to give a lecture to 4th-year IT students. During the session, they introduced them to the Adalo platform for creating mobile applications. Many thanks to the Gymnasium and Professor Nemanja Vasiljević for the warm welcome!
