SBR UK vs INT

Hi Sir,

I read on ACCA that the SBR UK version is required for those who aim to become audit partner within the UK.

Please could you confirm:

What does the difference between the INT and UK version entails? Can I prepare via opentution for any of them?

If someone sits the INT version, has to resit the full exam in future in case they decide to be auditor in the UK?

Thank you

Leo
