Test with a mark. Six works designed in the form of reports and credited by the lecturer.

Description of the organization and tasks of students’ independent work

Preparation for reports, using the literature indicated in the study program and consulting with the lecturer of the study course.

Criteria for Evaluating Learning Outcomes

The assessment of the study course test depends on the test task and the cumulative assessment of the study course reports.
A student can obtain a successful grade for reports if at least 50% of the report questions are answered correctly.

The test mark is calculated as the arithmetic mean of the average results of the defended reports
