Unless there has been a major change of which I'm unaware, score ranking should have nothing to do with it! According to the school's own oversubscription policy, the deciding factor in your case should be distance (after siblings and social/medical needs etc.)http://upload.reactcdn.co.uk/johnhampde ... s_2015.pdf
Who advised you that score is relevant? That system hasn't been used in Buckinghamshire for over ten years.
Good luck with the test results!
Edited to add.....might have been a bit hasty...does anyone know if late-entry tests etc. are handled differently for oversubscription purposes?
