Other foreign teachers'English training institutions, such as EF English and Weber English, are offline, but they also offer some online courses. Although they are well-known, their online learning is still in the exploratory stage. For example, EF English has a high reputation because of the endorsement of Hu Ge, but their annual expenses are more than 20,000 bar! There is no prescribed fee standard!
If you are eager to find online foreign teachers one-to-one, the choice of institutions is very good. What kind of services to choose, how to save money, which kind of training is the most practical and so on are to be considered. There is also that each institution has a trial class, they can seize these opportunities to listen to, have their own actual feelings, and make a clear choice.
This is what I have groped for so many years to sum up, hoping to help those who are looking for online foreign teachers one-to-one friends!
