Classification Type: Quantitativa (0-20)

Evaluation Methodology:
The character of this unit is namely theoretical. We follow the syllabus using examples and exercises with a proper level of difficulty. Interesting problems are proposed during the semester as a complement activity. Evaluation model A, each of the two evaluation weights 50% of the final mark. In the appeal exam it is possible to recover 100%.
