1, the single-mode exam is difficult, which allows you to see clearly your ranking in the city and provide reference 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.

2. The second model test is less difficult than the first model test, but if some students' scores in the first model test are not ideal, even if the second model test is very good, it is difficult to enter the independent enrollment of the favorite school.

3, the three-mode exam is iron, because in terms of difficulty, the difficulty of the three-mode exam is lower than that of the senior high school entrance examination. It is not so difficult for students to get high marks in order to increase their self-confidence, so this is a mock exam to boost morale.
