Teaching method
The course works with two theoretical classes a week complemented by practical classes where problems are solved and the main concepts covered in the theoretical classes are discussed.
Evaluation method
There is continuous evaluation throughout the semester or a final exam at the end of the semester.
The continuous evaluation consists of two tests.
