Assesssment methods and criteria:

Classification Type: Quantitativa (0-20)

Evaluation Methodology:
Lectures, Solving exercises, Practical work in laboratory and simulation. Practical Work: Practical Work is developped inside and outside the classroom and are evaluated through a report and presentation in class. They allow the student to develop competences of project, writting, presenting results, oral communication and ream work.
