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).
test can be repeated once during the semester and once during the repeat
pre-arranged personally or via email.
