Attendance not compulsory (but recommended)

Written examination with numerical exercises (single examination at the end of the course or alternatively two written examinations at the end of each half of the course) and an oral examination at the end of the course (open question/open answer). The written examination determines one third of the final grade, the oral examination determines two thirds of the final grade.
