Learning activities and methodology

Theory sessions. Problem sessions working individually and in groups. Practical sessions.

Assessment System

Regular call:
End-of-term exam (60%)
Continuous evaluation (40%)
In order to pass the subject two conditions are required:
1) To obtain a minimum of 5.0/10 in the global mark (End-of-term + continuous evaluation)
2) To obtain a minimum mark of 4.0/10 in the end-of-term exam separately

Extra call:
Only the end-of-term mark is taken into account.
Continuous evaluation is considered in case of improving the mark (under the rules of the regular call).

% end-of-term-examination 60
% of continuous assessment (assigments, laboratory, practicals...) 40
