Actually I think that, for some undersubscribed Lincolnshire grammar schools eg Skegness, Alford, (maybe Horncastle?) this may be the case and if one is reasonably bright one could get in with the basic familiarisation provided by the primary schools. However, for others eg King's or Caistor this is less likely to be the case. I still don't agree with the premise though that Lincolnshire parents don't tutor and Nottinghamshire ones do!
I think you're right Stocky, that we all apply whatever the rule is to our general situation! On this basic I think that Caistor's admission policy is brilliant!
(I do actually think that it provides quite a fair combination in that if you are in catchment a bare pass will do, after this it goes by mark, but obviously I'm biased!)
