Teaching methods

Classroom teaching by means of slides and blackboard.

Assessment methods and criteria

The learning assessment method consists of a written test lasting an hour and a half including an exercise plus two questions about class topics, followed by a brief oral exam.

The written test will take place during the exam sessions that will be made available at the end of the course.

During the written test, only the use of calculators and pen is allowed. You cannot consult textbooks, lecture notes and / or other material.
