Assessment methods and Criteria
The exam is written and consists of solving exercises in which the student must demonstrate that they have learned the theoretical concepts of the course. The exam can be taken in two partial exams (lasting 2 hours) or in a single final exam (lasting 3 hours) which includes the two modules of the course.
The evaluation is expressed by an overall mark out of thirty.
To take the exam you must register within the deadline set on the SIFA.
The grade is communicated to each individual student via automated email from the University's recording system and published on the Ariel website.
Students with SLD certification must contact the teachers sufficiently in advance for reporting and specific requests. Furthermore, the offices remind you that: "any forms/concept maps must be submitted to the teacher for inspection adequately in advance of the exam date (10 days before) to allow for appropriate evaluation. In fact, the teacher has the right to propose reductions or modifications if deemed necessary." In this regard, see the dedicated page https://www.unimi.it/en/study/student-services/services-students-specific-learning-disabilities-sld .
