Hi sumstuff, my DD has just got a place at BSG in Sepetember and I would just like to say that she comes from a Hampshire primary school and got in without any tutouring, apart form some practise papers in the Summer holidays of year 5.
I must admit I was a little anxious on the day of the Exam when alot of girls turned up in their very posh school uniforms, obvioulsy from the Independent schools, I thought that's it we have no chance!.
Would also like to add that DD Junior school had no interest in the 11+, although they did quietly praise her when they knew she had a place.
At the end of the day you as their mother will know if they are bright enough to get it, and do the kids want to go, my DD really wanted to go, so I think that was half the battle one.
Hope that was of some help, but not much I feel
