Assessment and grading criteria
The final exam includes a written test and, on specific request, an oral discussion.
The written test includes
- 10 closed-answer questions
- 2 textual answer questions
- 3 numeric exercises
The time assigned for the solution is 2 hours, and the maximum mark which can be achieved with the written test is 27.
The final grade is a weighted average of the scores of written test and oral discussion (weight about 0.8) and lab reports (weight about 0.2). It is possible to take a supplementary oral discussion (duration 15'-20'), addressing all the topics covered in lectures and laboratories, and get additional points with reports on specific topics, or preparing lecture notes to be reused in subsequent years. Detailed rules for reports and notes are given during the first lesson.
