Assessment methods and Criteria
The final examination consists of two parts: a written exam and an oral exam.
- During the written exam, the student must solve some exercises in the format of open-ended questions, with the aim of assessing the student's ability to solve problems related to the topics treated during the lectures. The duration of the written exam will be proportional to the number of exercises assigned, also taking into account the nature and complexity of the exercises themselves (however, the duration will not exceed three hours). The outcomes of the written exams will be available in the SIFA service through the UNIMIA portal.
- The oral exam can be taken only if the written component has been successfully passed. In the oral exam, the student will be required to illustrate results presented during the course and will be required to solve problems in order to evaluate her/his knowledge and comprehension of the arguments covered as well as the capacity to apply them.
The complete final examination is passed if all two parts (written and oral) are successfully passed. Final marks are given using the numerical range 0-30, and will be communicated immediately after the oral examination.
