Teaching method
Lectures sessions with datashow. Theoretical-practical sessions of aplications. Field trips.
Evaluation method
Theorethical component:
2 mini-tests, each corresponding to 25% of the final mark
Practical component:
2 reports, each corresponding to 25% of the final mark
Approval with a minimum score of 9.5 (scale of 20).
If students go to exam, the final mark will be 50% (exam) + 25% (TP1) + 25% (TP2)
