Type of delivery of the course

The course includes a series of lectures by the lecturer in which the topics covered by the course program and a series of recurring exercises to check the level of general learning. Due to the Covid-19 emergency, the teaching method takes place remotely through the use of a series of platforms that allow the transfer of teaching materials and the monitoring of the students' learning status. The moodle platform, teams, the uploading of audio and video lessons through one drive and the email are the tools used.

Attendance

Attendance is reccomended for at least 75% of the lessons

Type of evaluation

The exam includes a remote oral interview on the teams platform as required by article 1 of the rector's decree of 5 May to respect the restrictions imposed by the covid emergency situation
