There will be a final exam composed of two parts: one with theoretical questions and the other with numerical problems. The practices of the subject will be assessed through the evaluation of a group work. The final mark will be calculated as the average of the exam note (2/3 of the mark) and mark of the group work (1/3 of the grade). To pass the subject, both marks must be greater than 4. Students who don't deliver the work and request it previously, may opt instead for an additional part of the final exam.
