The BBO is free

We recognise the challenges schools and teachers face at the moment. We have secured funding to make the BBO free to all UK schools. Overseas schools will only need to pay £30 for unlimited entry.


UKBC will now exclusively send personalised e-certificates. In previous years, we distributed templates which teachers could distribute and followed these with posted personalised card certificates. From now on, we will only send secure e-certificates personalised to each student.

2021 past papers
