Assessment methods
The first part of the exam will test the student's ability in solution of problems (script: 6 problems/2 hours). The oral part of the exam is not compulsory. More information (in italian) are available in the official website of the course.
Oral examination, with questions aiming at understanding which are the concepts acquired by the student and his/her ability to explain the topics discussed in the course. The minimum score to pass the exam is 18/30, the maximum score is 30/30 cum laude.
