I am writing to you to express my appreciation to IELI. I have learnt so many key skills and essential knowledge which had equipped me to pass my OET. The most important thing that I have learnt was: think logically. I could never deny that I am a confused person; however IELI had helped me to overcome my weakness, and achieved my goal. I also would like to thank to Mrs Sue Trout, who gave me a great support, encouragement and patience. I could not improve myself so quickly without your guide. Many thanks to your teaching.
