Course (de)registration


For most courses you need to register online through Osiris. Your Solis-id is your login code for this programme. Registration for some courses is done by sending a registration request to the course coordinator. This is indicated in the course catalogue.

The Courseplanner is an online programme that helps you browse through the course catalogue and plan your study efficiently. 

The academic year has two semesters, each consisting of two periods. To be able to attend classes you need to register during the official course registration period for the courses you would like to take in each period:

If you have registered for a course that you do not wish to take, please deregister again through Osiris at your earliest convenience to open up a space for a fellow student. Your dossier will show an ND (not participated) or NVD (Not Completed), should you decide to quit a course half way. This may affect your cum laude status. Rules can be found in the Education and Examination Regulations (EER, Dutch: 'OER').
