All exchange and program students are exempt from a German language exam (DSH or TestDaF), which is otherwise required for international students studying at a German university. However, depending on the exchange agreement or the conditions of the external scholarship donor, a certain level of German language skills may be required. Generally, in order to follow courses and complete course assessment satisfactorily, German language skills equivalent to at least B1, preferably B2 (CEFR) are recommended.
