Modalità Valutazione

The exam is in two parts: the written exam usually lasts 2 hours and the oral exam follows. The written exam consists of a number of exercises (typically, from 3 to 5), aimed at veryfing the level of understanding of the theoretical concepts and the students' ability to apply the techniques explained in class.
