undergraduate students or high school students who tend to take IELTS

Currently, I am doing a PhD in University of Sussex. I have been working in New Oriental(one of the biggest english tutoring agency in China) for IELTS tutoring over one year and my students have received high scores(such as 8.5 for listening and 7.5for speaking). Generally, I have rich experience on how to improve their IELTs listening score and speaking score in one month. Besides, I am very energetic and expressive as a teacher and always have good friendship with my students!
