I'd like to express my thanks and gratitude to Nigel for his help, invaluable advice and beneficial essay assessments which helped me a lot in writing section.
The Speaking practice tests with Nigel were essential as he addressed some of my points of weaknesses in each part of the speaking test and how to overcome them. I got an overall band score of 7.5 with Listening 8, Reading 7.5, Writing 7.5, Speaking 7. I followed his instructions and apparently it worked.
Thank you Nigel once again!
