Ok the passmark this
is 220 which is the score reached by 28% of the local kids. OOC children have to reach the same level - usually they can offer to nearly all of the OOC kids who get the passmark.
There are a number of qualification appeals each year - with very variable success, though I have to say quite a low success rate (will find the figures shortly) .
Most I have heard of are usually within 1-2 points of the pass mark (last year it was 227 and the 224-226 had a good chance).
I think if you appeal you unfortunately have quite an uphill struggle as your DS is quite a way from the passmark in both tests, however you never know unless you try - but please bear in mind that it is an emotionally exhausting struggle.
Have a go at looking at the appeals Q&A at the top of the appeals page and also the figures I will find in a mo and come back with any questions,
