Course syllabus and organization

Single session

Lesson period
First semester
The lessons will be held on the Microsoft Teams platform (MTeams) and can be followed both synchronously on the basis of the first semester timetable and asynchronously as they are recorded and left available to students on MTeams and/or on the Ariel teaching site.
