Duncan is a passionate and dedicated teacher. I highly recommend him! It was an extremely useful and pleasant learning process. The conversations were enjoyable and thought provoking. His guidance is really helpful. He will provide you with a learning document with explicit explanations and will give you lots of advice on how to improve your language skills. I love our lessons! Thank you, Duncan !

After 5 hours of class, Duncan was a great help in giving me confidence in English. He was also very involved in helping me approach my future job interview. I highly recommend it. Again, thank you very much.

Another truly excellent class with Duncan: a challenging discussion, a profound conversation, as always with precise language feedback in a great atmosphere.

I just finished a set of lessons with Duncan, and I would say it was a great discovery that I found him on italki. He helped me improve my English with advanced English correction. During the lessons, he always tried to give me practical advice and to solve the problems that I currently have. Moreover, he encouraged me a lot and showed an enthusiastic attitude as a listener whenever I spoke. His immediate correction helped me recognise some mistakes that I hardly notice by myself. Furthermore, since he is an author, his corrections for my writing always suggested better expressions. As a result, he contributed to upgrading my writing skill. I highly recommend you, who want to learn advanced English and to improve your English properly, to have lessons with Duncan. He was one of the greatest English teachers I have ever met. Lastly, good luck with your writing, Duncan! :D

I had a session with Dr. Duncan, and it was extremely helpful for preparing for my second-round interview for an AI position. Dr. Duncan is an expert in data science, and his guidance gave me a much deeper understanding of what interviewers are actually looking for. He asked thoughtful analytical questions and helped me look at problems from the interviewer’s perspective, which was incredibly valuable. Every question he asked pushed me to think more clearly and explain my reasoning better. Dr. Duncan has expertise in many areas, and his feedback was insightful and practical. If you are looking for someone who can help bring out your best qualities as a candidate and prepare you for challenging technical interviews, I highly recommend having a session with him. You won’t regret it.

Duncan was once again hyper-focused on the lesson and gave me precise language feedback.
