Classification Type: Quantitativa (0-20)

Evaluation Methodology:
The lectures are used to introduce the concepts, results and methods to the student. In the problem solving classes, the student is expected to solve problems from the problem sets given, individually or in a group. In the normal season, the evaluation is composed by two compulsory written tests, each corresponding to 50% of the final grade. In the appeal season, students who have failed to pass the course during the normal season can choose between retaking one or the two tests, each corresponding to 50% of the final grade.
