Teaching method

Lectures sessions with datashow. Laboratorial sessions.

Evaluation method

- Continuous assessment with 4 elements of evaluation:

Evaluation of theoretical component: 2 Tests (each one 35% to the final grade).Weighted average of the 2 elements of evaluation must be equal or higher than 9.5 values (scale of 20).

Evaluation of the practical component: 2 Mini-Tests (each one 15% to the final grade)

Final rating: (0.70*Theoretical component) + (0.30*Practical component). Approval with a minimum score of 9.5 (scale of 20).

- Students without approval on the continuous assessment examination can proceed to the final exam, with the classification being defined by: 0.70 *Exam + 0.30*Classification of the practical component. Approval with a minimum score of 9.5 (scale of 20).

- Improvement of the classification requires a registration in the schedule examination period. The classification of the practical component cannot be improved and follows in the next year.
