Are you outside Altrincham as well? It just seems the done thing at our school that everyone goes to Kingsway, so DD is very much the odd one out. I have posted in other places about how she is quite worried about making new friends so it is great to try and make some connections. This is the other reason I have entered her for the mock exam so she will see she is not alone!
Yes outside Altrincham, many of her friends going to the feeder school, though one or two going to different schools also. Some from previous years have taken the 11plus for various schools including AGGS, and Altrincham G school has always been the one in back of my mind that I have thought may suit her. Though of course we haven't been round/got a feel for the place so I could have it completely wrong. I like the idea of a mock exam, and I totally agree when your DD sees others ( like my DD has ) in the same boat trying and going for it, it does rub off and I think this is why my DD is much more keen, she sees keeness in others so makes her strive a bit more.
For me, I don't think you can teach a child how to get in/pass etc. But you can give them skills to help work out some the questions they may answer, you can teach them relaxation skills for the exam situation. But most importantly for me I just want to give her confidence, and support and not push too much.
