I've been learning English as a second language since school and I learned a lot of words but I couldn't understand the grammar well. With this course is totally different because a lot of rules are becoming clearer to me and now I'm able to speak and write in Englihs much better.

The course is pretty useful. I bought the course because I was impressed with two previous Harry's courses. Actualy I was a bit skeptical at the beginig of the course because I had thought that I knew majority of common mistakes in English. But during the course I realised that I made so many mistakes before! No my English is much cleaner as I got rid of so many mistakes)))

Hi there. I’m Harry, and I’m your English teacher. Following over 30 years working in business I changed my career path and reinvented myself as a teacher, teaching English as a Foreign Language. I obtained my TEFL qualifications and have now been teaching English over 10 years both online using Skype™ and Zoom™ and in face-to-face lessons. I am successfully teaching to a very wide range of students across several continents. I specialise in Business English but happily teach people with any English learning needs. I have assisted many students to successfully pass a variety of English proficiency exams

The response to my teaching style is very positive and results in regular referrals of new students.

In this lecture we will review the most common mistakes in pronunciation. Before we start, I want you to remember one important thing

your accent has nothing to do with your pronunciation

Everybody has an accent. I have an accent. My children have an accent. Even the Queen has an accent.

Sometimes you are able to get rid of your accent or to change your accent (for example, if you move to a new country) but in most cases it is not easy.

However, your pronunciation is very very important. And in this lecture I will help you improve your English pronunciation.
