Thanks for your reply.
That is something that I haven't tried but I think I will give it a go. We have had a heart to heart this evening and I have explained that I am not angry with her just frustrated.
My other problem is that for some strange reason her school has decided to have their yr6 residential trip from this coming Sunday till the following Wednesday, leaving only Thursday and Friday to cram for the Saturday Nonsuch test. Having just come back from the summer holidays where not much study was done (purely my fault) I feel that not enough time has been left this close to the exam.
I will certainly try that plan, hopefully that combined with the discussion we have had this evening will help matters. I just don't want her to look back on this in a couple of years time with the view that I was being over pushy.
I think I will just pour myself another glass of wine and chill!!!!
