| Learning verification modality | The exam includes an oral test and the presentation of a technical report produced independently or in a group. The oral test consists of a discussion lasting about 30 minutes aimed at ascertaining the level of knowledge and understanding achieved by the student on the theoretical contents and methods indicated in the program. The oral test will also enable students to verify the student's communication skills with language properties and autonomous organization of the exposition on the same topics or theoretical content. |
