Accreditation TESOL Language

As a non-native english speaker, taking this course it helped me to review the basic english grammar and practice the language in a more structured way. During the course I remembered the techniques my english / German teachers have used when teaching the language. Now I understand more these techniques and I could organize one lesson better, as I know where to start and how to finish. One of my hobbies is learning foreign languages. With english language I got to the point where I feel that I can teach others, so it is on one side rewarding, and on the other unsure of the unknown, as I have no language teaching experience. I know how to teach science, but this is a different language.
