Chethan is from Vietnam and has been working as an English teacher for a while. He decided to take the next step and take our 120-hour online TEFL/TESOL course. He improved his language skills significantly after working through all 20 units of the course. He especially enjoyed the lessons on English grammar, classroom management, student elicitation and lesson planning. He thought the course is very well organized and easy to understand, especially for non native English speakers.
