Kryteria oceniania
Assessment will be based on documented abilities to solve problems (colloquies and written homework) as well as on theory understanding. Percentage of the final score:
- 50% problems solved in the course of written colloquies (the first colloquium in mid-term, the second colloquium at the end of the term, together with the written theoretical exam);
- 10% home exercises and problems;
-40% - theoretical exam (written).
The additional condition: theoretical exam threshold must be passed.
