Judging from the feedback from candidates and parents, the national 2-volume test questions are more difficult. Mathematics subject proposition scientifically regulates the difficulty of examination papers, adheres to the basic, comprehensive, applied and innovative examination requirements of mathematics subject college entrance examination, and implements the regulation strategy of "low starting point, multi-level and high gap", which plays a good guiding role in the selection of mathematics examination in college entrance examination.

1. My usual math 120. I can't do three big questions this time, so I have three choices. Do you find it difficult?

2. My mother is an invigilator. I just asked my mother if the math problem was difficult. My mother said it should be difficult to follow the answer.

To tell the truth, I just finished the second volume and read the questions in one volume. Emmm… does it feel like a simpler volume?

The third question of science in the second volume of Chinese (the fourth question of liberal arts) is a mathematical problem designed with volunteers participating in commodity distribution in a supermarket as the background, which examines students' mastery of basic knowledge and their ability to solve practical problems by using what they have learned.

The second volume, National Subject 16, takes the basic knowledge of solid geometry as the background, organically combines the problems of solid geometry with logical propositions, and examines students' mastery of relevant knowledge in many ways and at many levels.

For example, the science 12 question in the second volume of Zhongke is based on the autocorrelation of periodic series, and it is required to judge whether the four periodic series given in the question meet the conditions of the question, mainly to examine students' ability to understand and explore new concepts.
