It differs from faculty to faculty and campus to campus when exam dates are scheduled. In general exams for the autumn semester are scheduled in December and/or in January. For the spring semester they take place in June.
Check the academic calendar to find out when your study programme schedules exams.
In the past we have experienced some confusion about exam dates. The date of an exam is never final until shortly before an exam. Sometimes exam dates are announced already at the beginning of the semester. However, they are preliminary, not final, and can therefore not be counted on in connection with the planning of your departure.
Exam dates are not final until the end the end of November/May. It means that you should plan your departure according to the last possible day of exams - generally December 23, January 31 and June 30.
