Sorry, mattsurf - your earlier post seems to have been overlooked, but I hope I cover everything below.
At what point should I ask for the paper to be marked by hand, after the results are published or after she is not given a place?
It depends what the local arrangements are (if any). In Essex, for example, there's no guarantee of a re-mark. In Bucks, parents are told they must submit a request within 3 weeks of the publication of results. In Glos., there's an automatic re-mark for those who go to appeal. http://www.elevenplusexams.co.uk/appeal ... cation#b55
Given that I will need the school's support, would working at level 5B or 5C be sufficient or does she need to be working at level 5A or Level 6 to impress the pannel
It's up to your particular panel, and depends on local 'expectations'. If the school is 'superselective' or heavily oversubscribed, the more likely it is that the panel might prefer to see very high levels.
I believe that we have a strong case to appeal. Based on what happened and the missed section, what do you think?
Appeals are unpredictable, so I always hesitate to say.
Based on what you've told us, I certainly think it's worth an appeal to see what happens.
My question is, how do we handle the section that she missed - would an appeals pannel look at the evidence and the situation and agree to base the mark on questions answered
I doubt they would do that on their own initiative - but if you were to point it out to them, they would then consider it.
DD is doing mock SATs this week, if she does well in these, will they be taken into consideration?
Yes, they should be - if you provide written evidence for the appeal.
