19. Conditions for acquiring teacher’s signature and for taking final exam Attending the Lectures, Recitations and Laboratory Excersises.
20. Forms of assessment During the semester, two partial written exams are conducted (at the middle and at the end of the semester, duration 120 minutes), tests that are conducted during the classes and a test covering the laboratory exercises. For students who have passed the partial exams and the laboratory exercise test, a final oral exam (of duration 60 minutes) may be administered. The final grade includes points from the partial exams, tests and the final oral exam.
In the planned exam sessions, a written exam is taken (duration 120 minutes). For students who have passed the written exam and the laboratory exercise test, a final oral exam (duration 60 minutes) may be administered. The final grade includes points from the written exam, tests and the final oral exam.
The student should prepare a seminar paper and submit it by the exam date at the latest. It is not allowed to use books, lecture notes, written material and notes of any kind during the exam, as well as a mobile phone, tablet or any other electronic device, except a calculator.
