Minor point, but is it relevant that the OP is hoping for a place at Burnham? Won't an appeal be for qualification status only ie regardless of the school hoped for?
I'm not sure if the test was taken at Burnham, or if the child would like to go to BGS, but I agree - the appeal is definitely for qualification only.
Her other score was lower it was 106. She is currently on Level 4A for English which is the highest in her class at the moment. In maths she is again on 4A.
I'm sorry to say, anxiousp, that a score of 115 has only a 15% or so chance of success, based on last year's figures. In reality the chance of success could be lower, because the panel will certainly notice the 106.
It looks as if she is on target for 5c in English and maths, which is just about acceptable. 5a/b would have been better.
It sounds as if support from the school might be lukewarm.
Sorry I can't be more encouraging, but my feeling at the moment is that, without a lot more evidence of high ability, an appeal is unlikely to succeed.
