The whole agreement class means that the training from written test to interview is an agreement class. Generally speaking, unless you fail the written test and can't continue to participate in the interview training, it will be implemented as a separate agreement class.

The difference between the agreement class and the regular class may be related to the problem of non-refund. Take Tu Hua as an example, their agreement class will generally refund the fees according to your specific situation after the exam, such as failing the written test, failing the interview or not waiting for the interview.

It is estimated that other training institutions are similar.
