to think that some parents just don't get it?
Lots of the parents send their children to private schools/top state schools because they have excellent SATS/GCSE/A level results. This does not make the children (in general) any brighter but, they are taught to pass exams and when the results are published the schools promote them.
When my best friend studied at Magdalen College, she was one of the first people from our school in 1986 to study at Oxbridge. She studied Medicine.
She found that those students who had been pushed in the private/top state schools struggled far more than her (some to the point of getting kicked out) and she also questioned the validity of straight academic courses, unless an individual was actually going into teaching/lecturing, as even if someone was studying maths with a view to going into accountancy, they would still have to study professional qualifications post university.
There are plenty of Oxbridge and RG university graduates who haven't got transferable skills required in industry and those who have been pushed within an inch of their life at school and constantly spoonfed.
I believe most children fall within a spectrum of ability and there are the odd few who have special needs at either end of that continuom. I think some people are deluding themselves.
I am under no illusion regarding SATS/GCSE/A level results. The range of children in each school is broadly similar academically. What follows on is those who are in the top 5% in a challenging school are like my friend just as well if not better equipped to actually study a difficult subject and succeed in their chosen field.
I mean you only need to look at Royalty to see individuals who should never have set foot over the threshold of a uni
