My sons school will not tutor him in this as its a 13+ feeder school to public boarding schools and it only coaches/trains them for these exams. They also have no idea he is sitting it as thye are expecting him to stay there until 12 - which he probably will do unless he passes. I know in some GS areas some private schools specifically say on their website that they don't tutor for 11+ and some do.
When he sat his 7+ scholarship exams I spent a couple of months with him on the bond assessment tests in NVR, VR, English and Maths so I'm sure he'll remember this style although I'm not sure if they are appropriate for Essex.
Solimum - I don't think I'd be brave enough to turn down a grammar school place for a comp regardless of how good it is, but then they clearly have a daughter who doesn't conform to peer pressure - unlike me!
