My main university is another university in Berlin or Brandenburg and I am additionally enrolled at FU. How do I renew my enrollment
In order to re-register as a multiple enrolled student for the next semester, a certificate of enrollment for the subsequent semester from your main university with subject details must be uploaded in the Self-Service of the Student Records and Registration Office by March 31st or September 30th respectively.
If the other university is the Fernuniversität Hagen (Hagen Distance Learning University), you do not need to upload a certificate of enrollment.
