The Student Organization of Aalto University School of Busines, Mikkeli Campus. Probba was founded in 1989, the same year as the original BBA-program at the Mikkeli Campus. This is also where the name Probba originates from; Pro BBA, Latin for “For BBA”. Later the program was changed into BScBA, but the name for Probba remained the same. All the members are entitled to participate in Probba’s activity, which includes numerous events such as the famous Probba Orientation Week, Grand Annual ball, Career Day and many theme parties especially during the autumn months. We are proud of our crowd and we welcome new students every year with a special way. The Mikkeli spirit is a unique, unforgettable experience that can’t be explained – you have to come and see for yourself!
