Proof of payment of tuition fees
A "Bewijs Betaald Collegegeld (BBC)" is a declaration stating that you have paid the full statutory tuition fee of a Dutch university (WO) or higher professional education (HBO). If you then register simultaneously at another WO or HBO institution, you can submit the BBC at this second institution in order to be exempted from paying the statutory tuition fee there too. That is, you pay tuition fees at just one institution. Note, however, that you are only eligible for this exemption if you pay the statutory tuition fees (not the institutional fees).
