Course and exam enrolment

You can enrol via uSis for lectures, seminars, exams, papers, assignments and presentations. Enrolment procedures for certain activities can vary from programme to programme. In some cases you may have to enrol via the education administration office instead.

If you have questions about uSis please consult the FAQ first. 

Questions should be addressed to your education administration office

Course and exam enrolment

If you want to take a certain subject and / or examination (including re-sits), you have to register via uSis in a classnumber. Mostly this classnumber refers to an EXAMINATION, but you are kindly asked to enroll as soon as you plan to follow a course. Then the coordinator can use the list of enrolled students as an indication of the number of students that can be expected in the group. Find the numbers you need by choosing your Bsc of Msc programme in the menu below or by the TAB that indicates the study programme. To change the study programme, fill in your choice on the upper right hand side of the screen.
