How to evaluate the mathematics in National B Volume of 20021College Entrance Examination? How difficult is this year's topic? What changes have been made?
The new college entrance examination paper embodies the characteristics of anti-routine and anti-brushing, and pays attention to mathematical analysis ability, comprehensive ability and innovation ability. This makes many candidates feel embarrassed.

For example, the eighth multiple-choice question examines students' understanding of event independence with the help of classical probability. Because events can't be judged independently by simple observation, they can only rely on calculation, which goes back to the independent original definition. However, it is easy for students to ignore the understanding of basic concepts.

Another example is the 12 multiple-choice question, which examines the geometric extremum problem. Extreme value problem inevitably involves dynamic process, which is another knowledge point that many candidates can't master well. In addition, this topic also combines vectors, which reflects the comprehensiveness of the test questions and increases the difficulty.

Test paper features:

The test questions focus on integrating theory with practice, reflect the application value of mathematics, and let students feel the beauty of mathematics application. Integrating theory with practice embodies the characteristics of modern science and technology development and modern social production, and organically permeates the application of mathematical core literacy and mathematical thinking methods such as mathematical modeling, data analysis and logical reasoning, which is of positive significance to selection and education.

Focusing on core literacy and highlighting the examination of key abilities embodies the scientific selection function and education-oriented function of college entrance examination mathematics. Test questions highlight the essence of mathematics, attach importance to rational thinking, and adhere to the proposition principle of literacy-oriented and ability-oriented; Advocate the integration of theory with practice, apply what you have learned, pay attention to the important achievements of China's socialist construction and scientific and technological development, and design real problem situations.
