For information on your options to extend the processing time of your MA thesis, please refer to the website of the departmet's Examination Office (English text at the bottom).

According to information from the legal department, a reasonable limit for extensions due to acute illness is a maximum of half the regular processing time plus one day.

If the illness persists beyond this period, the Institute's examination board may demand that the exam will be retaken or recommend complete withdrawal from the exam attempt without consequences for valid reasons (in which case the exam is considered to be not taken and no attempt will be counted).
