"The only questions asked in school should be by the pupils", some wise person said.
Testing and exams reveal almost nothing about intelligence, merely memory.
We had so much testing at one school I taught at, that a teacher remarked, in a staff meeting:
"Do you pull up a flower every week to see how it's growing?"
Of course, his comment was ignored by management, all of whom were scrupulously  following the government's instructions on window-dressing.
Schools should be places where an insatiable curiosity about everything in life is the natural ethos.
Instead, our schools are busy ramming home the cerebral syllabuses of a very narrow range of subjects.  It is anti-educational.
"How is it that American education turns a torrent into a trickle?" John Holt asked decades ago.
Schools are becoming more and more anti-educational all the time.
Most people refuse or are too lazy to think for themselves.  'Received wisdom' is often exposed as a sham in many cases.  The nonsense so many believe is the only way covers a range of issues, education being one of them.  I laugh out loud when I hear someone say that British education is the finest in the world.  Wrong on so many levels.
Intelligent employers tend to place CVs, qualifications etc. further down the scale than careful questioning in an interview and reading the prospective employee's body language.
One last quotation, linked very much to the opening quotation:
"To give children answers to questions that they have not asked, is to make profound cynics of them."
