- Metody oceny:
- There is one mark for lectures and laboratory. The lectures are assessed based on the1 test. Student is obliged to get positive mark for that. For test it is possible to obtain positive mark answering for at least 60% of questions. The laboratory is assessed based on reports of each laboratory exercises.
The final mark for the course is calculated based on the 60% weight of mark for the lecture and 40% weight of mark for the laboratory.
