Feedback on the TEFL/TESOL course

I have been teaching English for 3 years but there is still room for improvement. I was afraid to teach Upper-Intermediate and Advanced students. I was looking for inspiration to add something new to my teaching style. When I read the course description I thought, "That's what I need". I was impressed with the course structure. I could get back to any chapter at any time to take some notes, that was really convenient. And a tutor, who helped me during the course, was highly qualified. He explained all my mishaps and provided positive feedback. I'm so proud that I decided to improve my knowledge with this course.
