As a rule, you may accept an offer actively until the end of the procedure (coordination phase 2). Please note that several possible offers only keep being available until the end of the decision phase. If you accept an offer, any and all of your other applications are withdrawn from the procedure. This is irreversible.
During coordination phase 2 your best possible offer is determined and that offer may be replaced by an offer of higher priority in the course of this phase. Any prior offers of lower priority are no longer available. You may actively accept this offer. In case you do not react, this offer is turned into an admission automatically at the end of the procedure.
An admission for a course of study that is not participating in the dialogue-oriented service procedure (DoSV) does not affect any applications on the application portal of hochschulstart.de. Applicants having received an according admission do still participate in the procedure.
