    Learning Activities and Methodology:

    In each week one lecture session (master class) and one practical session (in reduced groups) will be taught. The first is geared to the acquisition of theoretical knowledge, and the second to the acquisition of practical skills related to theoretical concepts. Additionally, students will complement the classes with work at home, using material provided on Aula Global.

    In addition to these sessions, four laboratory practical sessions in reduced groups (maximum 20 students) will be impart. These practices are mandatory.

    At the end of the semester tutorial session will be held. Students also have the possibility of individual tutorials.

    Assessment System:

    Final exam (obligatory): 60%
    Continuum evaluation: 40%
    - Laboratory report: 25%
    - Evaluation controls: 15%
    If the mark obtained in the final exam is lower than 4.5, the final mark of the student will be computed only with the final exam.
