Professors office hours
Students may go to office hours to talk to their Professors, according to the times published on the University staff webpages.
Professors receive students two hours per week. The office hours are defined at the beginning of each semester.
Most of the teachers' offices are in via Venezia, 8 building (it's the pink building near the gray one where you hold most lectures).
