Assessment
The activity ends with a written final exam (50%). During the semester, the students will have to prepare two reports (25%). The students’ activity during the semester will be also considered (25%).
All university official rules with respect to students’ attendance of academic activities, as well as to cheating and plagiarism, are valid and enforced.
