My son has just started at Bishops. He went to Winterbourne Earls school and this year they got 4 boys and 4 girls through out of a class of 25.
However, in my experience the state schools do nothing to prepare the children for the exam and your best bet is to find a good tutor to familiarize your son with the papers. Not sure about the private sector though and this year the test was fairer as you could not coach too much as there was a written piece of work included which was assessed in the case of a borderline.
We found ********fantastic. He advertises as the ********** and is very honest about potential and ability.
Hope this helps
