Evaluation Methodology
Final mark: : [laboratorial practice + technical report] (50%) + written test (40%) + presentation of the work developed in the practical class (10%).

Note:
Minimum grade of 10, for all the following components: Practical performance; Technical report; Written test.

The evaluation criteria are similar for both the continuous evaluation period and the exam period.
