Modalità d'esame

Two written test during the term with problems and questions similar to those solved during the tutored sessions.

Minimum of 18/30 for each of the two tests to pass the exam directly.

The oral exam is optional in this case, to improve the grade.

The oral exam is divided in two parts, like the course. If a student has average grade in excess of 18/30, but still one or two failed tests the oral is compulsory for the parts corresponding to the failed tests. An average grade of 17/30 implies that the student must take the oral exam on all two parts.
