Requirements for awarding credit points

Students will be credited if they have successfully completed all practical assignments, written tests and completed homework.

Description of the organization and tasks of students’ independent work

Preperation for for the test, using the literature indcated in the study program and consulting with the lecturer of the study coursei

Criteria for Evaluating Learning Outcomes

The assessment of the study course test depends on the cumulative assessment of the test task and the study course tests.
The student can successfully pass the test and the passing test if at least 50% of the test questions are answered correctly.

The test grade is calculated as the arithmetic mean of the results of the tests passed.
