20. Forms of assessment During the semester, two partial written exams are provided (at the middle and at the end of the semester, with duration 120 minutes), test from laboratory exercises For students who have passed the partial exams and the laboratory exercise test, the exam is considered passed. The other students take the final exam on whole material (duration 120 minutes). The points from the partial exams/final exam and the test are included in the final grade.
