Assesssment methods and criteria:

Classification Type: Quantitativa (0-20)

Evaluation Methodology:
First Season - 2 tests (50% each) with theoretical issues and practical problems related to the subjects taught in the discipline - has objective to assess theoretical and theoretical and practical knowledge integrated in two tests that covers various topics of the course. To pass the course the student has to acquire both: Final grade = mean {1st Test, 2nd Test} >= 9,5val; 1st Test grade >= 6,0val; 2 nd Test grade >= 6,0val; Second and Third Season - 1 exam with theoretical issues and practical problems related to the subjects taught in the discipline - has objective to assess theoretical and theoretical and practical knowledge integrated in one exam that covers various topics of the course, which focuses on student's ability to relate parts of yhe syllabus. To pass the course the student has to acquire: Final grade >= 9,5val
