Criteria for Evaluating Learning Outcomes

The assessment of the study course examination is cumulative. It is made up of the grades of the examination, tests during the semester and home assignments.
The grade is successful if at least 50% of the questions of tests or the examination are correct.

The assessment requirements of home assignments and a practical task of the examinations is included in the instructions of the home assignments or practical task.
The examination grade is calculated as an arithmetic mean of examination assignments grade and the mean of grades obtained during the semester (a mean arithmetic grade of tests and home assignments).
