Learning assessment

The exam includes the verification of the level of achievement of the previously indicated training objectives. The exam is an interview in which the level of knowledge and the ability to present the topics covered during the course will be assessed. The interview will consist of at least three questions.
The evaluation will take into account the correctness and the quality of representation of diagrams, schematics and figures; of the correct use of symbols and formulas; of the ability to exhibit and master the topics.
