Completing a doctoral or licentiate education often requires taking some courses. The General Study Plan for each programme should specify the extent of the course part of the research education – this part can amount to no more than 120 ECTS for a doctorate, or 60 ECTS for a licentiate.
There may be some courses that are mandatory in your programme, according to the General Study Plan. You should check early on about such requirements.
The courses that you take, both mandatory and elective, should be in the Individual Study Plan. You should talk to your supervisor and the person in charge of research education about elective courses.
The university has the obligation to provide you access to both the mandatory courses in your program and other courses that it has decided, through your Individual Study Plan, that you should take. This means you cannot be asked to pay a course tax.
