My DD1 sat the 10+ for Whitgift and Trinity in 2009. Initially we were using the exams for the 11+ GS but the nearer we got to the exam dates, we thought he could be in with a good chance of getting in. Luckily he did, we chose Trinity over Whitgift and we have no regrets. He loved it from day 1, made some really good friends in his form and had some brilliant experiences. As Third time round mentioned, some of the boys all had places in the teams (though they did get worried about the new Yr 7 boys!) and I have noticed that my DD1 and his friends have really stuck together, so far, in Yr7 even though they have been split into different forms.
I am trying to encourage DD2 to got he same route as his older brother but he is adamant that he is staying at his Primary School. I will not push it with him but I would honestly prefer for him to do his Yr6 at T or W; from what I have seen at his school, Yr6 is a bit of a waste.
Ps, my DD1 did the tour on Saturday; he told me that he told 2 families to go for Yr 6 entry as it's the best thing ever!!!
