 The four-week in-class course and the combined course, they have teaching practice, so practical teaching experience at a training centre. The online course has no practical experience involved in the course at all. Those online courses are all taken 100% completely online. But of course, the need not to be in a training centre means they are more flexible. They can be studied in the trainees' own time and at their own pace. The combined course is a mixture of the two, so you have the flexibility of the 120-hour online course, plus the prestigiousness of the teaching practice at one of the training centres also. The differences between the courses can be a little bit involved. So, if anyone has any further questions, they can contact us any time, 24 hours a day.
