B.I.S.S. stands for Bochum International Summer School. The B.I.S.S. offers courses during the summer break, usually in August, that are taught by both distinguished professors from abroad and faculty members from Bochum. B.I.S.S. economics and management courses are meant to be complementary to the regular course offer, i.e. they are usually not lectured during regular semesters. All courses and exams are in English. By enrolling in the B.I.S.S., students may obtain credits towards their Master’s degree.
