    10. Assessment

    During the semester: Written test (min. 40%)


    During examination period:  Written exam with optional oral exam.

    Passed midterm test is required to sign up for exams.


    Final mark is calculated as:

    Weighted average of test grade (45%), written exam grade (45%) and oral exam grade (10%) if the exam is passed. In case of unsuccessful exam, the final mark is fail (1).

    11. Recaps The midterm test can be repeated once during the repeat period.
    12. Consultations At times pre-arranged personally or via email/Teams.
