The best preparation for Grammar school entrance exams is private tuition.
We decided a different route, and it worked fortunately.
We sent her to Kumon which she loves to bits, for maths and English tuition.
We also did a lot of past exam papers, and verbal reasoning papers.
I could not stress more the verbal reasoning. It was a component of the entrance exam, and believe me comprehensive primary schools do not teach verbal reasoning skills explicitly.
Thanks for that link. I have heard some of the mothers talking about this but I never looked into it further as we already have a tutor for Maths whilst my wife does English and I do IQ. I think I'm still going to check them out. There is a centre not to far from me so I'll give the lady a call and she what she has to offer.
The verbal reasoning is a good point that you bring up. I think they refer to it as comprehension at our school. EDIT - I just checked it out and we haven't come across this terminology. I will most definitely check this out.
The current 'hot' subject is comprehension. I get my daughter to explain to me what she has read in her own words. I'm finding this useful to gauge her understanding of written English.
