Assesssment methods and criteria:

Classification Type: Quantitativa (0-20)

Evaluation Methodology:
Oral and written presentations of the course syllabus. Application of practical examples to consolidate the theory. Two tests, each with 50% weight in the final evaluation, in order to assess theoretical and practical knowledge. This way the student can, over half, evaluate its performance and change strategies as needed. Exam: final exam that covers various topics of the course.
