Type of delivery of the course

Teaching is organized with lectures. Some lessons are dedicated to practical insights of what learned during the theoretical lessons, through exercises guided by the teacher.

Type of evaluation

The verification of the learning takes place through an oral test in which questions are proposed in order to verify the understanding of the concepts and the ability of the student to apply them in real contexts.
