|20. Forms of assessment||During the semester, two partial written exams are taken (at the middle and at the end of the semester, with a duration of up to 90 minutes) and tests , which are conducted during the classes. The final grade includes the points from the partial exams and tests.
During the exam sessions a written exam is taken (with a duration of up to 120 minutes). The final grade includes points form the exam tests.
A special instruction published before each exam regulates the manner of taking the exam and the use of teaching aids and electronic devices during the exam
