A series of exercises will be proposed aiming at consolidating knowledge and stimulating the ability to solve problems. The evaluation of the subject, expressed on a scale of 0 to 20 values, will be done at various times including 2 midterms (40%+50%) and individual work to be developed outside the classroom (10%). If the weighted average of these moments is equal to or greater than 9.5, the student will be successful in the course, otherwise the student will be able to take a global frequency (90%) to which the mentioned 10% will be added. In the final exam (100%) the student will be able to improve the grade. The minimum passing grade in this assessment is also 9.5. Assessment criteria are explained at the beginning of the semester.
