The English - arrggghhh! I still haven't seen "Longitude" but "Captain Corelli's Mandolin" was bad enough and we did "Tess" yesterday....hmmmm, what can I say? I gather "Tess" was another one that went down in the annals of history, as far as Essex English is concerned
I too dread the English - wish I could do it for her.
On results day, we allegedly get both raw and standardised scores, plus something which gives us an indication as to whether they've passed or not, based on the last few years' results. I feel the same way that you do, as to the usefulness of the previous years' results - I'm not sure how the Chelmsford schools' imposition of a catchment area will effect numbers etc and pass marks
I'm trying to remain optimistic that we'll get a pretty good idea but I'm a real "Doubting Thomas" 
Having to sail your ship alone, without a tutor, is a lonely old business, isn't it, fraught with more than the usual doubts that an 11+ parent has? It's all about choices and I suppose we have to face the good and the bad. I know I couldn't trust a tutor and if things go awry, then I can change tack really quickly and the responsibility rests with me. However, it would be nice to have an outsider tell you that your child and the work you do together, is on-track and that you don't need to have so many self-doubts.
Looks like for our two DC's, it's an out-of-catchment school as the best "Plan B" . I truly wish it wasn't like that.
