Learning Assessment
Learning Assessment Procedures
The exam consists of verifying the theoretical and practical knowledge of the topics covered during the course through ongoing tests reserved only for students who attend at least 75% of the lessons and a written test for the remaining students, with a maximum obtainable grade of 26/30.
Both types of students, if interested in improving their assessment, can also take the oral test
