Evaluation

Throughout the course sevearl activities will be proposed. Such activities may be solving exercises, practices, discussion of cases or carrying out work in which the theoretical knowledge of the course are applied.

 

At the end of the semester a written exam in which the overall content of the course will be evaluated. This test has a minimum weight of 45% of the final grade.

 

A recovery exam will  also be conducted for those students having carried out the activities of the subject have not passed the continuous assessment.
