Type of Assessment
Intermediate tests
Oral discussion of a project draft
The final exam aims to ascertain the acquisition of learning outcomes in terms of knowledge and skills by conducting an oral interview based on a project developed during the course.
The intermediate tests consist, in each case, of 3 exercises aimed at verifying knowledge on three-phase systems, on electric machines.
The oral exam consists of an interview aimed at evaluating the student's communication skills and at bringing out the knowledge of the topics discussed and discussed in the course.
