According to Finnish law, every university student in Finland must be a member of the Student Union. TuKY is the student union of Turku School of Economics. Most importantly, membership gives you the right to use the medical services provided by the Finnish Student Health Service. Membership also allows you to have low cost lunches at student cafeterias, offers discounts on travel and accommodation in youth hostels, and provides reductions on tickets to concerts, etc.
The student union of TSE TuKY organises a wide range of free time activities, including various sports, a choir, and parties. Erasmus Student Network (ESN) is a pan-European student organisation whose goal is to support international student exchange. ESN arranges various leisure time activities, trips, meetings and events especially directed towards exchange students, international students, and internationally minded Finns.
