"It feels More like... we're selecting the students most likely to be reliably competent & last the whole 5-6 years on our course."
Don't know whether you're a medic or not but if you are, then I'm highly concerned your school's selection machine has been barking up the wrong trees all this while if "reliable competence" (whatever that means) that can last 5-6 years is all you're looking for in your medical students. May as well select all marathon runners for guaranteed stamina!
And if you're not a medic, then I suggest you're in the wrong job as I can't see how a supposedly highly efficient machine can function efficiently and seamlessly with a major wrong part fitted on it. Imagine the RFU at Twickenham having as its head coach someone who'd never touched a rugby ball in his life trying to select players for the England team!
"I don't even know what that word 'best' means to the poster who wrote it (or to anyone else). . .World class? More like battle for survival under immense strain, sadly."
It was I who wrote the words, 'best' and 'world class'. And I must admit it doesn't surprise me a jot given the above that you don't understand these two simple terms.
According to the World Directory of Medical Schools, there are over 2800 operational medical schools from Afghanistan to 'Zululand'. And if the United Kingdom have 2 in the first 3; or 5 in the first 15; or 7 in the first 25 out of these 2800 schools, then in anybody's language it is absolutely World Class and Best!
What that's really, really sad is for someone pertaining to be involved in the UK medical schools is to devalue the profession.
