- Metody oceny:
- There is one mark for lectures and exercises. The lectures are assessed based on the 2 tests. Student is obliged to get positive mark for both of them. For each test it is possible to obtain positive mark for answering for at least 60% of questions. The exercises are assessed based on reports from the blocks of problems defined by the teacher.
The final mark for the subject is calculated based on the 60% weight of mark for the lecture and 40% weight of mark for the exercises.
