Generally, there are three model exams, which are very formal and unified throughout the city. Each of the three model tests focuses on quality, that is, a thorough investigation and preliminary evaluation of the college entrance examination. The second mode pays more attention to the effect, that is, the college entrance examination is basically determined. The third mode pays more attention to morale, that is, encouraging candidates to go to the examination room with confidence. Therefore, there is definitely a gap between the college entrance examination results and the college entrance examination results, and the gap is quite large.
