Grading is absolute (not relative) and done in relation to the course's learning goals. Therefore the distribution of grades fluctuates from year to year based of the students' pre-requisites and preparation during the course - and how well the course has been taught.
Grades are given according to the scale 5-U (with ECTS equivalents in parenthesis): 5 (A, B); 4 (B, C, D); 3 (D, E); U (Fx, F).
