Attendance

Attendance is important in order to acquire regularly and continuously the concepts of the Course, the theoretical and numerical methods that are applied to both didactic and project cases. Interaction in class promotes attention and effective learning.

Type of evaluation

It is possible to take a mid-term test about halfway through the course. If you pass this test, an oral exam will be held on the rest of the course.
