ITTT TEFL Course appeared to be very informative with interesting and useful information. I was searching for a long time for a good TEFL course as there are a variety of them on the Internet but I don't regret about choosing the 170-hour ITTT TEFL course with specialization in teaching online. The units in the course were well-structured with a lot of illustrative materials. All of the information was provided in the easy to understand way what is a great help in passing the tests at the end of every unit. In general, I strongly recommend to apply for ITTT courses. They have a good support system and whenever you need help or additional information they will reply in a fast but professional manner.
