Course performance is assessed and expressed in grades. Each course or the Bachelor Thesis is graded in integers or half marks (0.5). The grading scale is set from zero to ten. The minimum passing mark is five (5). The exams results are announced by the instructor and are sent to the Secretariat of the Department within fifteen days from the course examination. Re-examination or review is not permitted. Exceptionally, the Department may decide to re-examine a course in case more than 85% of the students examined failed it.
