I've a same understanding as StephiB and that's what I've heard from some of the parents from Bucks and Berks.
If you would like your dd to take a practice exam why not try making her sit for mock exam through some 11+ mock providers?
There is a service in this forum itself. Visit for further info http://www.elevenplusexams.co.uk/11plus ... mock-exams
I also agree with KB. they don't want children to be much familiar with what they are going to undertake on the exam day. In fact I believe for that reason only CCHS has not provided us with proper sample papers like CSSE.
The best thing to do is preparing our child for any best/worst possibilities. I'm doing the same with my dd and we're confident to face any type of papers as we don't know which one to expect. Above all in the end it's the child's ability and how the exam day starts for them.
Better check with CCHS.
