Assesssment methods and criteria:

Classification Type: Quantitativa (0-20)

Evaluation Methodology:
2 Exams: The Exams are intended to assess the theoretical and theoretical/practical knowledge acquired by students. 5 practical laboratory assignments: The assignments are assessed by writen reports (3) or oral presentations (2). These assignmente allow the students to apply the acquired knowledge (either in the laboratory and in terms of simulation), and also allows them to develop writing skills, improve the presentation of results, their oral communication skills and teamwork. There is a 6th assignment, related to objective O8, which is not evaluated.
