Training methods and skills are very important for civil servant interviews. Teachers' teaching level and teaching experience are very important. It is recommended to listen to the teacher more before making a decision. Regarding agreed classes and non-agreed classes, I personally suggest to look at the written test scores and interview level. Some people's speech ability and speaking skills are good in themselves, and with good written test results, it is not bad to sign up for a non-agreement class. On the contrary, it is more appropriate to choose an agreed class. Of course, if economic conditions permit.
