Before I started working with John, I did not know what parts of my essay were losing marks. More importantly, it is hard to identify all of the problems and mistakes that you made in your own writing and speaking unless some professionals check and point out for you. Therefore, I really appreciate all of the feedback and comments from John and see my English has been improved. I would strongly recommend training from John to anyone who has problem to enhance their English, particularly in IELTS writing and speaking. Thank you so much, John.
