In order to take the ICDL Advanced exams you must have an ICDL Skills Card.
It is a virtual Card, on which the passed ICDL exams are recorded. The ICDL Skills Card has no expiration date, therefore, those who have obtained the ICDL Full Standard certification or converted the ECDL Core Skills Card into a ICDL Skills Card do not have to buy another Skills Card.
In addition to the ICDL Skills Card, you must purchase the Advanced exams you wish to take too.
Instructions to the payment procedure and other relevant information about the ICDL Advanced certifications, including the scheduled dates of the exams, are published on the website www.unibocconi.eu/itec, in the 'ICDL Advanced' section.
