Description of the organization and tasks of students’ independent work

The organization of independent work during the semester takes place independently by studying literature using the consultations of the lecturer. Fives seminars have been developed and publicly defended.

Criteria for Evaluating Learning Outcomes

The assessment of the study course exam depends on the assessment of the examination assignment and the cumulative assessment of the study course seminars.
A student can get a successful mark on the exam if at least 50% of the test questions are answered correctly and 3 workshops are presented.
The exam grade is calculated as the arithmetic mean of the two, the exam assignments and the average marks for the presented seminars, which is calculated as the average of the marks of the seminars arranged in the study course.
