I think I'm glad we won't see the paper or know the raw scores for each paper. It would seem pretty pointless without knowing the questions.
You should be able to find it out at the appeal.
Interestingly, some like to think they can use the scores for the different papers to see who was heavily tutored to get through the exam, and who was just naturally bright.
The theory goes like this: The first paper is a 'recycled' paper, used every 4 or 5 years (which is why they don't let people see the paper itself - you might pass the questions on), and features more or less the question types that are taught by the tutors. The second paper is new every year, and has different types of questions, which none of the children have encountered. The questions in both papers are of similar difficulty.
Tutored children will find the first paper easier than the second, hence the second is often thought of as 'harder'. Untutored will find them equally difficult.
A good score in the first paper, and a poor one in the second, suggests that the child was very used to that type of question, and not naturally able (without tuition) to work out the answers in the second paper.
When parents are asked in passing what preparation the children did for the exam, some parents tell the truth, others may not do (I know this from chatting in the playground). It can be proven - say - if a child from a school known to spend 2 or 3 years tutoring their pupils for the 11+ has the score style outlined above, and the parents waltz in saying they just did the practice papers at home. Gotcha!
Don't forget, though that there are loads of tutored children who did get in, and likewise ones who were untutored, or just genuinely did the practice book papers. There are also other reasons that a child did better in the first paper - for example, there was a major disturbance in the exam room during the second paper.
As for us (parents / panalists) not seeing the papers - I'd love to, just to try one out after all the years since I took the 11+ - I always enjoyed that type of test.
