Yes, I am in one of there named parishes ... But there is still about 6 or 7 parishes closer then mine x
If you are in one of the named parishes for MGS, and your DS scored 390 plus, which I understand to be the case, you should not have any problem with MGS, and distace should not come into the equation. In previous years all 390+ers in the named parishes have obtained a place, accounting for about 60/70% of the intake, and it has then gone to distance for the under 390ers, going out to about 5miles.
But, are you sure you are in one of the named parishes for MGS. I understood from earlier posts you are in Seal, which does seem a long way out.
