You are automatically enrolled for the courses in the 1st semester of your 1st year only. From the 2nd semester (period 3 and 4) onwards, it is your own responsibility to enrol for all courses (required courses, optional course profile ones and courses that are part of your approved optional minor). This means you will need to enrol for your 2nd semester courses yourself.
As of the academic year 2018-2019 you can enrol for a maximum of three courses (22.5 ECTS) per period. It is not necessary anymore to ask permission to follow a 3rd course. You can only enrol via Osiris Student and during the designated enrolment periods.


You can enrol for the courses during the enrolment periods via Osiris Student. Please visit the Course Catalogue for content and schedule information.

Please note! Avoid overlap in timeslots.

Besides your enrolment for the courses, you also enrol for the tutorial groups. Of course you need to follow certain rules (pdf).
Ensure that you enrol during the regular enrolment period, because you will only be guaranteed participation in a course if you enrolled on time.

If you decide not to participate in a course, then you must terminate your enrolment. You can do this via Osiris Student until the end of the second week of the period in which the course is taught.

If you do not terminate your enrolment, the remark ‘Did not participate’ will be registered in Osiris. This means that if you wish to take this course in a following academic year, you will automatically be assigned to repeaters courses.

Academic year 2018-2019 

  • Termination of enrolment period 1: up to and including 23 September 2018
  • Termination of enrolment period 2: up to and including 25 November 2018
  • Termination of enrolment period 3: up to and including 17 February 2019
  • Termination of enrolment period 4: up to and including 5 May 2019

The course options for late enrolment are very limited: only those courses that have places left over will be open for late enrolment. You can enrol for the limited places during the late enrolment dates via Osiris Student as of 0:00 hours on the first change date per period.

Avoid overlap in timeslots.
