Exam description

Please refer to what is written for the course of Engineering Physics

Assessment methods

The modality to check the achievement of expected learning outcomes consists in the evaluation conducted during the exam, as well as in the sharing of the results of exercises performed during the course.

The written exam verifies the achievement of an adequate level of operational expertize such as to allow an effective practice in the field.

The theoretical comprehension of the subject is verified through oral questions regarding the different topics taught during the course.
