LEARNING ACTIVITES AND METHODOLOGY:

Theory sessions
Problem sessions working individually and in groups
Lab-sessions and computer sessions with mathematical software

ASSESSMENT SYSTEM:

End-of-term exam (60%)
Class exams (20%)
Lab sessions (20%)

In order to pass the subject, two requirements need to be met:

1) to have a MINIMUM mark of 4.0/10 in the end-of-term exam;
2) to have a minimum  overall mark of 5.0/10 (weighing 60% the end-of-term exam mark and 40% the mark of the continuous evaluation).
