3 Laboratory sessions

Learning Activities and Methodology:

- Master class, sessions of questions resolution in reduced groups, students presentations, individual sessions, and personal student work for theoretical knowledge (3 ECTS).

- Practical sessions of laboratory and sessions of problems in reduced groups, individual sessions, and personal student work for practical knowledge (3 ECTS).

Additionally, collective tutorship can be included in the programme.

Assessment System:

Continuum assessment system based on short tests and laboratory reports.
Master class, sessions of questions resolution in reduced groups, students presentations, individual sessions, and personal student work for theoretical knowledge.
Practical sessions of laboratory and sessions of problems in reduced groups, individual sessions, and personal student work for practical knowledge.

A minimum grade of 4.5 in the final exam is required to take into account the continuum assessment.
