We know that she put a silly ending to her story which possibly could have lost her valuable marks.
Should we mention this at the appeal?
It might be worth a very brief mention if the panel ask you why you think she underperformed, otherwise I suggest not.
What sort of questions should we ask the panel?
They ask the questions!
What points should we emphasize at the hearing, would it be best to focus on the fact that she only just missed the pass mark and she didnt perform on the day, maybe due to nerves. Her overall academic performance is good and she attends a high performing school.
It's best to focus on all the academic evidence you can gather. See Q&As, B11.
You say her overall academic performance is good, so, like ealingmum, I wonder why the school is not supporting?
