Some people say that "the first mold is gold, the second mold is silver, and the third mold is iron".

The single-mode exam is very difficult, which allows you to see clearly your ranking in the city and provide reference for volunteering for the senior high school entrance examination. Moreover, the results of the model test largely determine whether you can participate in the independent enrollment of some key high schools and apply for an ideal school.

The second model test is less difficult than the first model test, but if some students fail in the first model test, even if they do well in the second model test, it is difficult to enter the independent enrollment of Xinyi School.

The "three modules" exam is iron, because in terms of difficulty, there is no difficulty in the middle school entrance examination. In order to increase self-confidence and make students feel that it is not so difficult to get high marks, it is a mock exam to boost morale, which has low reference value for the results of the senior high school entrance examination, and the results of the three modules are also less helpful for signing the contract.
