I have just completed a 120-hour TEFL course and I am satisfied with this experience. I can say that I enjoyed ITTT online course. Firstly, it was very convenient for me, because I have a part-time job. Secondly, it is easy to navigate within the system. Here you can study Units one by one. The following Unit opens as soon as you finish the Test and you can do several Units per day (its good when you have a day-off). Finally, the course itself is well structured with many teaching ideas/tips and useful examples. For some topics, the common troubles are listed with possible ways of solving them, which I found rather useful. In my opinion, tests weren’t that difficult, however, sometimes they required knowledge of previous Units. For me it was important to include phone number on the post address and after my request, I got an immediate answer that it was done (special thanks!). My certificate is on the way and, in addition, I gained some knowledge, so I am satisfied with my choice.
