One of the following specializations (SP) with the associated modules must be selected for semesters five and six. The choice of specialization is made in the fourth semester. The choice of specialization is generally binding; a change of specialization can only be made within four weeks of the start of lectures in the fifth semester. There is no entitlement to all specializations being carried out in every academic year, even if there are not enough participants (determined in advance by the Dean of Studies).
