    10. Assessment

    a) During the semester:

              Written test, 40% required to pass

     

    b) During examination period:

    Written exam with possible oral exam (in case the result of the written exam is at least pass (2) final mark can be upgraded by one mark).

    Passes test and signature are required to sign up for exams.

    c) Final mark is calculated as:

    Weighted average of test grade (20%) and exam grade (80%), 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 semester and once during the repeat period.

    12. Consultations

    At times pre-arranged personally or via email.
