I think you are right about the fees, W has already caught up with KCS's fees for lower school... Brilliant your DS got a scholarship, well done!
I am getting a bit panicky now, because my youngest is in year 5 and unless he gets into a grammar, we will be trying to get him into W. I can't send him to T, because it's bad enough with boys supporting different football teams and I couldn't cope with them squabbling over their respective schools as well! Plus, T doesn't have much basketball going on, which W does, and basketball is my youngest's thing.
BTW, assuming he passes the grammar tests (which may be just wishful thinking), do you know whether it's better to disclose on W application form that we are applying for grammars as well, or is it better to keep it quiet? It's hard to decide how to go about it - we will not know until March whether he got a grammar place or not and I don't know whether admitting grammar applications is likely to diminish a chance of being offered a place at W... Do you have a feel for this sort of thing from your interviews?
