The teaching is organized in two theoretical lectures and one practical shift per week. Each theory lesson lasts 1h and each practical session lasts 2h. In practical classes several exercises indicated by teachers or suggested by students are solved. Evaluation consists an intermediate test around the middle of the semester, with a 40 percent weighting, and a final exam, with a 60 percent weighting. In case the grade in the final exam is higher than that of the intermediate exam, that grade will prevail.
