The landlord has any questions to ask me. You can rest assured of the teaching quality of EF. The best cities in EF are Beijing, Shanghai, Guangzhou and Shenzhen. The quality of teaching is guaranteed. There are small classes, large classes and many life club courses. There are no more than 4 students in small classes and no more than 25 students in large classes, and there are many life club courses. You can register according to your own interests. Online courses are also very different from other courses. Class every day on the hour, as long as you want, and the online courses are in line with your current learning progress, so that you can review them conveniently. And the study counselor keeps track of your progress. I think you can actually go to the scene and have a look. The customer service there is very good, even if you don't go in the end, people won't do that.
