A semester contribution of EUR 72.00 is payable when you renew your registration. This consists of the student services contribution of currently EUR 52.00 and the EUR 20.00 semester bus pass fee. Please note that failure to pay the semester contribution on time (i.e. within the re-registration period) will result in your not being registered for your programme for the next semester and may lead to your being de-registered from the degree programme altogether.
