Type of delivery of the course

Lectures and recitations at the blackboard. Explanation of the theory presented via discussion of examples. In the case of an extension of the health emergency from COVID-19, all the provisions that regulate the methods of carrying out the teaching activities and student assessment will be implemented. In particular, the lessons will be held remotely through the Microsoft Teams application, and any material related to the lectures uploaded on the Moodle platform.

Type of evaluation

Oral exam. The student before taking the oral test has to take a take-home exam.
