I also heard the same as Chad. If anyone is in doubt, please contact the school. They won't be able to tell you the score needed for this year, but they should be able to tell you last year's one.
Worried, the pass rate for this year 11+ must be the about the same as for the previous years, 25%, unless there was a lot less applicants. The pass score being a standardised score, it represents how well the child performed by comparison to others, so there will always be high and low scores.
I don't know about the schools you have heard off, but in my view, if some schools did better that usual, either there was less applicants, or some other schools will have done worse.
The scores posted here have also been generally high, may be because the parents had enough information to tutor their child well.
