An interuniversity programme is a programme that is organised by several universities. Have you enrolled for an interuniversity programme (that the University of Antwerp is involved in) at a different institution? Then chances are that you will also need to take some programme components at the University of Antwerp. In addition to enrolling in your home institution, you will also have to enrol at the University of Antwerp to be able to use the facilities. You will need a proof of registration at the home institution. Once you have this document, you can then enrol by following the standard procedure.
