You can get a place on a degree program with restricted admission by applying to the university of your choice in good time.
'Härtefallantrag'
Under certain conditions, applicants with a health impairment can apply for immediate admission to a degree course via a hardship application, regardless of their grade and without a waiting period. A small number of study places are allocated to applicants via this hardship quota. A current specialist medical certificate must prove that a waiting period is not reasonable for certain reasons.
There are other special applications for improving the average grade or the waiting time.
