Personally, I prefer online English for gifted scholars and online interactive classroom for Shanghai Real People and Company, but it is an online classroom, and I can go wherever there is a computer at home. A real small class, a class of four people. European and American local professional teachers teach through the Internet abroad, and China teachers are mostly from China who study abroad or live abroad. The most important thing is not to listen to hundreds of people in a teacher's class, so there are many more opportunities to practice oral English with the teacher.
