I read this in the Sunday Times and it's still niggling away at me.
Why would these parents think it's a good idea to pay their children per GCSE grade A/A*? Surely if by the age of 15 the child hasn't worked out that it's in his/her own interest to get the best grades they are capable of, then something has gone a bit wrong? And if they do work hard and it all goes hideously wrong for some reason, then they're going to need serious tea and sympathy, not a cut in allowance.
People in London do this for 11+ seelctive secondary entry as well, which is possibly even worse -- one of dd1's acquaintainces from swimming was promised £100 if she got into school A or £50 if she got into school B.
Is it just me, or is this barking?
