Type of Assessment
Written examination which foresee the solution of some exercises of electromagnetism.
Oral examination on the extended program, with discussion related to laboratory experiences reports.
It is possible to achieve exemption from written test exam through two written tests, carried out in the first and second semester. The exemption from the written examination are valid only until the September exam session after the end of the course.
