Did you really mean "elite internationals"?? Gosh, that sounds horribly colonialist 🙉 North Korea has its own elites by definition (ppl who govern the country), but I guess they are not "elite" enough for you...
I merely stated the simple fact well known to everyone that Chinese, Russians and Arabs used to love sending their offspring to British PS and splash their cash here, surely that's no news to anyone? The tide has already turned though, even the Arabs are moving their money elsewhere - just read the news and figures.
Not sure what sister schools have to do with the topic related to schools on British soil 🤔
DC1 sat US SATs as we were considering the US. You are right, you could get scholarships but it's not that easy. Also, I was really shocked by the standards of SATs - DC did no preparation at all and had a minor head injury literally half an hour before the tests, but still got scores in the range good for Harvard. It was obvious US school education was even worse than British. Unis may be different (though I don't understand how, if you have such an intake), I have no first hand experience of unis so can't really comment.
Agree on the point of limiting access to education.
Anyway, sorry for the long off-topic OP. I was just interested in the take on German vs US unis as we considered both at one point and DC actually sat a few tests (I would not consider the US now though).
