Singapore's nascent FM residency training is understandably subpar as it's very much in it's infancy with primary care as the bulwark of a nation's healthcare system a new concept locally (Singapore healthcare system is still very much specialist-driven).

They should have adopted the Australian RACGP training programme which is world renowned for producing specialist GPs able to act as mini-specialists in all specialities due to the need to be able to practice independently in remote areas. Canada is another country with superior FM training but it's demographics are less like Singapore's compared to Australia.
