Assesssment methods and criteria:

Classification Type: Quantitativa (0-20)

Evaluation Methodology:
Exam: The exams (2, 35% each) aim at assessing the theoretical and practical knowledge. Thus, the students are able to evaluate their performance along the semester and change their learning strategies if necessary: Project: The project allows students to carry out research, including reading scientific papers and magazines. The students should elaborate a report and present a seminar. (30% of the classification of the C U)
