| Requirements for awarding credit points | |
| Test with a mark. Three successfully evaluated independent works. | |
| Description of the organization and tasks of students’ independent work | |
| Preparation for independent work, using the literature indicated in the study program and consulting with the lecturer of the study course. | |
| Criteria for Evaluating Learning Outcomes | |
| The evaluation of the study course test depends on the evaluation of the performance of independent work.
The student successfully marks the independent work, if each work is completed at least 75% of the assigned task. The test mark is calculated as the arithmetic mean of the average results of the performed independent work. |
