sendsummer sorry if I seem contradictory. Thank you for your post. My main points are that the UK is so far behind on languages that it would be very easy to outshine any language student educated in the U.K, wherever you are from, whatever language you speak.
DD has been massively disadvantaged here in Spain with regards to her English, but as me and fussychica have outlined, we have been to enormous lengths to ensure our DC's still did well at English, against the odds. Following the English curriculum. NOT EFL. Which is what is taught in schools.
She does her schooling purely in Spanish/French/Valenciano, I do the rest.
I am also an English teacher so have that advantage. None of this has been easy at all. While you are all getting a black belt in karate or whatever, I am making sure my DD speaks perfect English. Every night.
Yes, I was amazed at the level of English my DD's friend spoke. She will not be doing English at university, that is for sure.
My point is, being bilingual is not the easy option people out there that some seem to think it is. Not at all.
Happy to say though, DD speaks Spanish like a Spaniard and English like an Englishwoman. I am proud of that, if she wanted to do Eng Lit or Spanish, or Modern Languages, good for her. But, she wants to do maths (which people good at languages are also very good at)
Nobody is cheating the system, that makes my blood boil. As Lavenderblue has said, she will do an Eng A level and probably a Spanish A level, privatively, as standard, as extra to her IB.
