See the plan of lectures and seminars:

If possible, you should choose the first seminar in your specialization (if not, you can ask one of the other professors to be your tutor and help you write a research paper for a theological journal during your studies).

An additional (second) seminar is outside your area of specialization. Formally, you should attend two seminars, but if your tutor does not conduct a seminar, he indicates to the teacher of one of the seminars of your choice the grade that he puts in the USOS.

Your tutor may be a professor whom you know from the classes which you attend.
