Have a look at the mark scheme for the History source based exams. I'm sorry to say this but this exam is all about understanding the questions. FWIW DD did this one in Jan and got a U!!! I looked at her answer and couldn't believe it but once we looked very closely I could see that she had missed the point, but not completely, so very harsh marking. She did much better with her resit result, she got yesterday, but I had to help her to understand how to answer the question.
I was really chuffed with myself as some of the points I picked out were worthy of an A (described as being the more astute candidate answers).
As for people feeling they have failed their DC's, don't feel like this.
Mine is at a state school and her 6th form have weak depts., unfortunately for DD, mainly in the subjects she is studying. Some pupils did get A* A level results yesterday but you are talking exceptionally brainy and I suspect, in fact know, that their studying is topped up with private tutors, which being a low paid single mum I cannot afford to do.
Also you see good private schools where the majority of pupils get A grades and it really makes you aware of the inequalites of life, guess it's just a fact of life really, isn't it?
I've just bought DD a new dress to say well done, after all isn't a B grade at State School equivalent to an A at private
