Teacher Charles' knowledge is excellent and strong in many fields; so, in this sense, the tutoring with him, is very productive in many topics. In my specific case, he helped me giving me a new and different approach to Business English, and also to handle in a better way the anxieties and insecurities in business presentations, and corporate meetings. I highly recommend teacher Charles!
Jeremy recommended me to record my own voice. (I did not like that.) However ,I can recognize that I have improved when I listen to my voice which was recorded before. In addition, Jeremy knows business well. He teaches me business English such as writing a business e-mail and making a presentation. I feel confident when I speak English in my office recently. Jeremy teaches me not only English but also communication ability. Thank you, Jeremy!
