Accommodation is included in closed classes for China students, but not in other ordinary classes. I have participated in the closed class interview, and the training intensity is very strong. However, there is nothing I can do about the exam, and the effect is still good. However, this kind of closed class is more suitable for people with a certain foundation, because the closed class usually starts some time before the written test or after the interview test. If you have no foundation at all, I'm afraid it's difficult to learn.
