My dd is the only girl from her primary school going to whsg and I was worried that she would no longer be happy with this outcome, hence me starting the thread on the Sutton forum (whsg 2013). With all the year 6's talking about their new schools and who is going where, I thought she may have regrets about putting whsg first when our second choice is also a good school, just not grammar.
I am pleased to say that there is no evidence of this. She knows what a good school she is going to and that many girls will be in the same boat. In fact, this forum seems to have found her a potential travel buddy. She is ready for this new phase in her life and realises she can now have school friends and home friends. I am sure that the induction day will relieve a lot of your dd's anxieties.
Best of luck with this though.
PS what is LBBD?
I think the OP is talking about Westcliff High School for Girls in Essex, not ?Wallington (??) - LBBD is London Borough of Barking and Dagenham, I suspect.
Assuming the above...
C2C train to Chalkwell for WHSG / WHSB / St. Thomas More well-used by pupils of those schools travelling in from further up the line - plenty of contact with the opposite gender on the way to and from school, then, even if there is apparently rather less contact between WHSG and WHSB than outsiders might assume from the fact that the two are essentially on the same site
If anything, one is more likely to see local boys and girls walking into school on their own - the "railway children" tend to drift up and down from the station in companionable groups.
Also, the sixth form is mixed
