Requirements for awarding credit points

To get credit points, you must have worked for all practical works and have successfully passed 5 control tests.
In order to obtain the final assessment of the course “exam”, five tests must be successfully completed, as well as working on all practical works and participation in practical work on fish farm.
Working out late hours should be coordinated with the teaching staff.

Description of the organization and tasks of students’ independent work

Independently study the latest scientific articles on fish farming as mentioned by the lecturer, from which questions are included in the test.
The student has to take part in the practical work trip to the fish farm.

Criteria for Evaluating Learning Outcomes

Successfully passed five tests. At least 70% of the questions must be answered correctly in each test. Independently studied work is included in the test.
