Officially it is not possible to drop a course after the switch period. If you were unable to deregister in the Elective Registration System due to personal circumstances, you can contact MSc Programme Management via this form

As an exception we will process the deregistration request after the switch period. 

All deregistration requests received once the course has started will not be processed. This means that if you do not plan on completing the course after being enrolled, you will receive a ”NO” grade: this counts as a no-show and does not affect the GPA or cum laude judicium.
