An interesting course. I did the 120 hour TEFL Course which is the minimum required for a TEFL Certificate to be accepted as a formal teaching qualification. I found i-to-i to be a good provider. I found their website and progression easy to follow. The tutors when marking the essay and plan are thorough, so you will get feedback, even if you pass. As the feedback given also includes ways to improve your lesson plans for the future. The exams at the end of each module were helpful, as it allowed you to reinforce what you learned previously, and is highly useful for the final exam. Overall I am pleased with the quality, the only issue I had was that it focused too much on the different English exams. What i-to-i could have done perhaps, is to allow the student to choose which exam they want to teach, for example IELTs, TOEIC, TOEFL or some other exam...
