Hercule Poirot would be amazing at preparing for the viva. He’s meticulous and organised. He looks deeply into matters and isn’t satisfied if an explanation only satisfies some of the details. Often he has a companion – Captain Hastings, Ariadne Oliver, Chief Inspector Japp – who can offer him support and a different perspective on the case at hand. And after he has taken in as much information as possible he rests his little grey cells until they are ready to sing to him.
Poirot would ace a viva. You can too, n’est-ce pas? Be organised; find an ally; rest your little grey cells.
