Participation in exercises is mandatory, while attendance at lectures is recommended. Earning a credit is conditioned on active participation in the exercises, with a maximum absence of 20% of the total number of exercises. If the exercise is conducted as a 2-hour session every two weeks, the absence is calculated based on the 2-hour exercise sessions. If a student does not earn a proper credit, they have the opportunity to obtain it by successfully completing a credit test. There are no retake opportunities for the credit test or other ways to obtain the credit.

The course is concluded with a written exam. If the student disagrees with the grade received, the exam is considered graded with an F. The student has the opportunity to obtain a new grade by retaking the written exam, and the previous grade will not be considered
