Just to respond to the comments regarding the alternatives to grammar in Bournemouth. I started looking for a school for my son in Bournemouth a couple of years ago and I will need to find a school for my daughter in a couple of years. I think the choice for boys is even worse than for girls with regards to GCSE results and value added. I even took the unusual step of looking at private schools but I found there were far more options for girls in the area.
We looked round all the schools and then considered moving out of the area as we didn't think any of the schools were right for him.
As he was in the top sets at school we spent some time working with him at home and he got into the grammar.
I agree that the grammar schools do well because they cream off the best students, who have good support at home and they give regular homework. I think the discipline is also an important factor. My son has only been at school for a few weeks and has already had detention for forgetting homework (husband's fault - I was away for a few days, left a meal in the fridge, put guitar and Rugby kit required for the second day by the front door, 2 days lunch money in pocket - can't think of everthing...
I think the detention has given him a kick up the @rse and the school is moulding him into a more responsible individual already (which is going to make my life a whole lot easier).
I hope my son won't get penalised by the univerties because, coming from grammar, he is expected to get good results. I have to say, being uneducated myself and running my own businees I might well look more favourably at a CV from an achiever from a comp rather than a grammar (don't tell my son)
