Teaching methods

Lectures supported by audio-visual materials.
In principle the lectures take place in classroom. Possibility of remote streaming for non-resident students who cannot participate in the classroom lectures.

Assessment methods and criteria

Oral examination including:

- Short seminar (max 15 min) on a topic chosen among those presented in the course

- Questions on the different topics in order to check the general confidence of the student with the concepts treated during the course

Final mark will be based for 1/3 on the seminar and 2/3 on the oral examination.

Should the Covid-19 pandemic impede the oral examination in presence, the exams will take place in remote, however method and evaluation of students will not change
