For medical (visits, illnesses) and legal (appointments for residence permits) reasons, it is possible to inform the management of the need to be absent for part or all of the lesson. It is not necessary to send medical or legal certificates. Instead, send a message via the site’s messaging system to the teaching directors and the professors in charge of the hours you will be absent. The communication must be made in advance or, in any case, as soon as possible. If you report your absence late, it may have already been recorded in the system and counted. Justifications for lesser reasons or minor needs (visits to relatives, renewals of public transport passes, etc.) are not acceptable.
