nothing wrong is you say.
because you don't know what you don't know. definitely some gdfm holder super experienced and as good as any fcfp but no gaurantee, definitely also gt m.mmeder who scrape through and somewhat dodegy like myself but balance of probability is someone who passed went rhrought a formal apprenticeship system , pass proper exams by many other experienced doctor will be better.
based on what u say might as well medical student teach medical student la, since all got many As at A levels , correct Bo?
