The personal appointments for the oral exams will be announced at our Web site after the end of the withdrawal period (1 week).
In case you are not available on single days of the examination period, please send an email to our secretary Fr. Ufermann. Please observe the following guidelines:

  • Do not mail us earlier than 4 weeks before the exam date, and no later than August 30.
  • Most likely, exams will only take place from Tuesday-Thursday, so requests for Monday or Friday cannot be considered.
  • You should be available full-day on at least one of these three days - in case you are available for a half day only, we will try our best.
  • In case you registered for 2 exams, both will be held together.
  • In case you are not at all available in the above period, we will try to find a separate exam date for you. Only in this case, send an email directly to Prof. Fuhr, but not before July 1.
