If you can get a score of about 120 in the national paper, there is no big problem if you get a score of about 140 in the national paper. There are differences in the difficulty of examination papers, just like some local papers and national papers. Of course, the difficulty is different, because the level of education development varies from place to place, but the level of education development in some places is obviously quite good, which is incredible. However, the difficulty of the paper is not high, which may be due to the regional educational resources, but in the final analysis, the three volumes of the country are simple because those places are vast and sparsely populated, and it is not easy for children to go to school and there are not so many educational resources.
The scope of the investigation is different. The content of the first national exam may be a little deeper, and the content of the third national exam will focus more on the application of basic concepts, but it will not be particularly comprehensive. After studying for so many years, we all know that the difficulty of any problem will definitely rise rapidly once it reaches a higher comprehensive level, because a high comprehensive level means that this problem will involve a lot of knowledge learned before, but if there is no section, you will do it.
There are relatively many questions in one volume. The last big problem of mathematics and the last big problem of comprehensive management are basically not for normal people. Based on the knowledge of junior high school and senior high school, it is basically impossible. It may be much easier to use some methods such as advanced mathematics linear algebra in universities and middle schools, but people in high schools have basically never been exposed to this thing, so the difficulty of this exam is hierarchical.
