Learning activities and methodology
The teaching methodology will include: - Theoretical lectures in large groups, where knowledge that students should acquire will be presented. The course weekly schedule will be available to students and they are expected to prepare the classes in advance. - Resolution of exercises by the student, which will serve them as a self-assessment and to acquire the necessary skills - Problem classes, during which problems are discussed and solved - Tutorships
