Teaching method

Lectures combine the presentation of the theoretical concepts with the use of slide projection containing schematic illustrations with important aspects related to the subject and the resolution of exercises by the students. Group resolution is encouraged. At the end of each class the problem is solved.

Evaluation method

The continuous evaluation of the discipline consists of three individual tests without consultation, The tests classification worth 25%, 40% and 35% of the final grade. A minimum score of 9.5 is required on the average of the o tests.

In case the student does not have approval in the first component of continuous evaluation will have right to go to a final examination. A minimum grade of 10 (9.5) values ​​on the scale of 0 to 20 is required in the exam grade.
