Wetherby is a great school! So that would not be bad either. Being extremely happy is great.
Bear in mind that, in Colet Court, I believe, there are only 36 places for 7+8+. I wonder where all of those schools that claim they put children there fit... My feeling is that only 1 or 2 boys (if at all) out of the "known" schools go to Colet Court. That is a great success, considering the numbers! Every school I visited claimed they put boys in Colet Court. If I counted all of them, they clearly exceeded the 36 number! We have to be realistic. Wetherby, Westminster, Colet, Sussex, Latymer etc. they are all great. And the important thing is to find a school that is right for the child.
I did not like many of the schools I visited simply because they were "exam preparation machines". Children were not happy in the classes and there was a great lack of attention to other subjects that are not tested in an exam. I would rather have a little "Renaissance" genius than a "Maths" machine. All aspects of education are important, including knowing how to behave in public and sell an idea. This brings success at the end of the day, not answering what is Q in QxQxQ=1881.
(And I may not be right but I was admitted in Harvard Law myself!)
So I think Bassett is a great choice. Fingers crossed and take care! Thanks for the advice.
