Teaching method
Lectures and problem-solving sessions, lab sessions
Evaluation method
Theorical assessment: 3 mid-term tests or final exame. Weight of 1st test: 40%. Weight of 2nd test: 30%. Weight of 3rd test: 30%. Final exam has 100% weight in final grade. Minimum theorical assessment grade: 9,5 val.
Laboratorial assessment (grade >9,5) can follow two methodologies:
a) 4 lab sessions with a quizz before each session, 1 report and its discussion, 30% of the final grade
b) 2 lab sessions with a quizz before each session, 1 project execution and its report discussion, 50% of the final grade
Final mark:
a) 0,70 theory mark + 0,30 lab mark;
b) 0,50 theory mark + 0,50 lab mark.
