Re-registration at Reutlingen University
If you spend more than one semester at Reutlingen university, you will have to re-register for each subsequent semester. You must do this by the deadline - see Semester Dates - otherwise you will have to pay a fine. (A reminder will be sent to you, but in German only.) Re-registration (Rückmeldung) simply involves paying the appropriate fees, and can be done either by bank transfer or online using your Campus CaRT.
If you re-register online, you must have a German bank account from which the University is entitled to debit your fees. Online re-registration has the advantage that it is effective instantly, whilst a traditional bank transfer may take up to 10 days. With online re-registration you can immediately download all the certificates you need for the coming semester and also extend your Campus CaRT's period of validity.
Further information is available here (in German), or from your Programme Coordinator.
