Mrsmcruff yes my DC are all in the state system. Two of them are at a SS. I said the brightest children - the ones the 11+ is trying to reach (as opposed to the wealthy hot housed ones) will be working at L6 by the end of Y5. Some of the very brightest ones will be working at L6 by the beginning of Y5. Certainly in maths.
No, they won't. Well, you tell me they will in your area. I don't know where you are, but there must be a huge variation in state primaries countrywide, if this is what passes for normality in your area. I think you probably don't realise how unusual this is in the state system. There are some very bright children at my ds's large primary school, most of whom could probably pass the VR and English paper with minimal familiarisation, but they would be struggling with the maths paper, because the school does not differentiate effectively in maths until Year 6, (where the 'top table' will be heading for L6) and most certainly does not teach the year 6 syllabus below year 6.
given that I have 3 DCs in the state system, 2 of whom have taken and passed the 11+ without any need for the sort of tutoring being described here
Just out of interest, what was the format of the 11+ taken by your dc, in terms of VR, NVR, maths etc?
