I have been involved with language learning, teaching, and testing for the past 20 years. I have worked as an IELTS examiner and examiner trainer for the British Council in China for 13 years and so I know the test inside out. I have personally interviewed over 8000 IELTS candidates from China and so I know exactly what kinds of linguistic and cultural problems Chinese candidates face when they take the speaking or writing test. I have 2 teaching qualifications issued by Cambridge University and have taught IELTS to hundreds of Chinese students. I also speak fluent Mandarin and so I am fully aware of the problems Chinese speakers face when learning the English language.
