But even though Ravell is happy to coach these children, she doesn't approve. 'Coaching is all part and parcel of the system,' she says. 'I don't agree with children sitting exams at age seven and eight - it's proven that boys don't mature as quickly diagnostically. Basically, those who gain the entry places to schools such as Westminster and St Paul's are of a "type"; they're looking for mature and independent children who can deal with the pressure,' she says. This rules out the creative, the unusual and the immature. Though everyone claims the children don't feel the pressure of the exams, it's simply not true. Peter Kendall, a chartered clinical psychologist, sees the victims. 'These exams have all sorts of consequences,' he says. 'They're setting children up for failure. Coaching makes it worse. Just because they get in the front door because they've been coached doesn't mean they can do it. Moreover, children aren't stupid,' he adds. 'They know you don't sit an exam without a result. It's pass or fail and they know it.' Most, needless to say, fail? and they always blame the school.
