Thanks for your replies.
I contacted the school we were most interested in. Her levels are fine, and are indicative of the levels she would need to be at to be of "grammar" material. She would need to sit an 12/13+ exams in NVR, VR and Numeracy, followed by papers in English, Maths and Science and a language of either French, German or Italian. Which for her, would be the sticking point - she takes Spanish at her current school.
We've managed to iron out a few of the problems we were having (nasty girls being mean
), and have a guarantee that she will not be in the subject groups with the same girls next year. They will also be setting the subject groups, which presently they only do for Maths and Science. So hopefully all a lot more positive.
Hopefully only got to worry about her younger sister's 11+ in September now!
It never ends, does it!
