See how over the age (EDGE) I am!!!!
You are certainly very well travelled Tolstoy.
Spoken to my DH re the raw score situation in Bexley and he has the following theory:-
If 40 questions = 280 marks then each question is worth 7 marks. So with 1 wrong answer 7 marks are lost which mean 16 marks were lost due to age (23 - 7).
In Bucks approx 7 marks are taken away for September birthdays - but Bucks scores are out of 180 so 16 from 280 doesn't seem too different.
But this doesn't take into account their formula so may be irrelevant
End of DH theory
But saying all that an older DC will still lose out if the test was easier and may not pass.
Sometimes knowledge is not a good thing!!
That website is a nightmare and should not be allowed! They should have one test date for all which would prevent any distortion of the raw scores needed to pass and prevent DC's passing who have no intention of taking up the place! (prune face) Actually mad but was a bit scared of the disturbing mad face available!
