The content of the agreement classes in different institutions is different, but generally it is necessary to sign an agreement, which may be, for example, passing an exam.

Agreement classes need to be signed, and non-agreement classes don't need to be signed. The fees charged by agreements are different from those charged by non-agreements. Generally speaking, the charges of agreement are more expensive than those of non-agreement.

For example, as soon as the written test results of civil servants come out, Nanjing's public examination training institutions have been in full swing in the "battle". Interestingly, the assault classes, training classes and regular classes in previous years have all disappeared, and they have all been changed into sky-high "agreement classes". What is an "agreement class"? Is that the trainer signs an agreement with the training unit. The agreement will state that if the interview fails, the corresponding fees will be refunded; If you successfully pass the interview, the fee will not be refunded.
