Registration can only be withdrawn in written form. The e-mail (stating the reason) has to be sent to the secretary of the ZEMS within 14 days of the start of the course (4 days for intensive courses during semester break). Consultation with the teacher or simple absence are not considered as a withdrawal.

In the case of a withdrawal within the specified deadlines, the fee of the course - minus a 5.00 cancellation fee - is refunded.
