REQUIREMENTS FOR STUDENTS:
Students are required to regularly attend lectures and seminars and actively participate in them. Furthermore, students are required to solve and submit homework assignments in order to receive a signature, and to attend two tests during the semester.
GRADING AND ASSESSING THE WORK OF STUDENTS:
The final exam consists of written and oral exam, the final grade is the average value of grades obtained on each of them. A written exam can be replaced by two successfully solved tests during the semester.
