Öntevékeny Csoportok Irodája (ÖCSI) is one of the largest student organizations at the university, consisting of almost 150 members. Since 1972 we assist the integration of the newly accepted students to the university by organizing events. Our main happenings are the Freshman Camp and Freshmen’s Ball, however, we provide other fun activities and camps in order to make everyone’s first year memorable. The members of our organization, called instructors, also find the time to arrange as well as participate in team building activities or in workshops where they can strengthen their skills in different fields and spend some quality time together. We offer numerous ‘working sections’ linked to event organizing so everyone can find what is suitable for them.
