Navigate to the 'Studies' section and select the 'Study journal' tab
Select the semester for which you would like to obtain a certificate of enrolment or student ID. If the semester has not yet begun, it will appear grayed out. The border will turn green once you have successfully selected it. Then select the round icon in the lower left corner labeled either “Re-enrolment” or “Enrolment.”
You can now download the documents as PDF files at the bottom right of the page.
Please save the "Studierendenausweis" on your mobile device so that you can show it digitally if required. You can print out the certificate of enrolment 'Studienbescheinigung KHB - Ausführlich' for submission for official purposes
