There are not many full-time English training schools in China because of the limitations of venues, funds, manpower, students and teachers. Compared with learning English on the job, the biggest advantage of closed English is that it can calm down, put aside all other thoughts, have no pressure and worries about work, just like students who go back to school for education, study carefree and wholeheartedly. Such learning conditions are very rare for adults. In the learning process of iBS, students are immersed in the world of pure English all day, away from the interference of life and work, and only concentrate on learning English.
No matter which English training class is good, some people can't, mainly depending on whether it suits their own needs. It is best to apply for a course experience to see if the experience suits you.
