Quick answer
Internationally trained veterinary surgeons need Grade B (350) in OET Veterinary for RCVS (UK) and AVBC (Australia) registration. The RCVS requires an overall Grade B with B in three sub-tests and at least C+ in one; the AVBC requires B in all four in a single sitting. The Writing sub-test tests your ability to switch register between colleague veterinary specialist and pet owner. Most marks are lost on Genre & Style: register mismatch with the intended addressee.
