You have to complete 3 credits in “other activities”: labs, internships, etc.
Internships are activated through COSP – a University service.
Labs are listed in this page, and are normally 20 hour-seminars with mandatory attendance and with a maximum number of participants activated under the scientific responsibility of a professor. They may be even external activitries formaslly recognized by the faculty.
We recognize even external language certificates (at a higher level compared to the one offered at SPO), and the ECDL – European Computer Driving License.
If you work, you should ask prof. Pedersini to check if the faculty does recognize that activity in order to fulfill the 3 cfu requirement.
