Termine für mündliche Prüfungen

For office hours preferably suggest a date on which also examinations take place (see below).


Oral exam policy changed

Due to the enourmous extra effort caused by cancelling exam appointments,
I decided to join the official system and allow for exam registrations only
during the official periods and after registration in PAUL. 

Look for the next possiblity to register in PAUL.

A registration for an exam appointment is only possible after you are registered for the exam in PAUL. 

An exception from this rule needs a specific reason
(e.g. being an exchange student on visit of Uni Paderborn
 or previous agreement with me of a different exam date).

If you think, your case is an exception, please send and email and name the reason for an exception.


The next possible exam dates:

  • Mon, 27.08.2018
  • Tue, 28.08.2018
  • Wed, 29.08.2018
  • Wed, 10.10.2018
  • Thu, 11.10.2018
  • Tue, 30.10.2018


Further exam dates in September/October/November will be announced by the end of August .


Please choose one of the shown exam dates and fill the following form

and send it via email to  Prof. Dr. Stefan Böttcher.
