A VN friend is looking for a good English school.
She is well-paid and professional, and doesn't want to be bothered with a dodgy school with inexperienced teachers. She is around 5 on a real IELTS test now, with writing worse than speaking.
Her aim is high enough certification on IELTS or the like for study and work overseas.
She says she finds what she calls the "old way" of teaching doesn't work very well. I am not sure exactly what that means, but I think she must be striving for a latest method that isn't just vocab or grammar or whatever the "old" way is.
There are some like at the British Council or Wall Street, but they are very expensive.
Any ideas, especially from VN people who have learnt English, on the best value towards the top end? Does one have to pay the high price, or is there better value slightly down the prestige level?
