Extended data:
National Grade A: The overall difficulty is high, and the investigation involves many knowledge points, and some challenging topics emerge, such as: finding the surface area and volume of polyhedron, extreme value of function, calculation of definite integral in calculus, sequence, mathematical induction, etc.
National Volume B: Compared with Volume A, it is slightly less difficult and pays more attention to the assessment of basic knowledge. It also covers a wide range of knowledge, including straight lines and curves, plane vectors, trigonometric functions and so on. With the increase of class hours, the difficulty difference between volume B and volume A is gradually decreasing.
National New Curriculum Standard Volume 1: According to the requirements of the new curriculum reform, it emphasizes quality education and ability training, pays attention to the cultivation of students' thinking ability and the examination of practical application ability, and the topic is moderately difficult. It involves the application of quantity, function and analytic geometry, sequence, probability, etc.
The second volume of the national new curriculum standard: relatively difficult, focusing on examining students' comprehensive quality. Including trigonometric functions and solid geometry, series, calculus and so on.
Beijing Paper: Compared with other provinces, the difficulty of Beijing Paper will increase, and the examination content involves deep-seated thinking ability and operational skills. Knowledge points related to limit, derivative, calculus, etc.
Tianjin Volume: The difficulty of mathematics test questions is close to the national volume A, and more attention is paid to the examination of basic knowledge and methods. There are many kinds of test questions, and the distribution of test scores is reasonable, involving knowledge such as sequence, analytic geometry and probability.
Shanghai Volume: The difficulty of the examination questions is moderate, and the content of the examination is mainly based on the national new curriculum standard, focusing on theoretical knowledge and practical application. It involves plane vectors, trigonometric functions, derivatives, calculus and so on.
To sum up, it is predicted that in 2023, the overall trend of mathematics test difficulty will develop in a high direction, but with the advancement of the new curriculum, the test content will gradually shift to focusing on practical application and cultivating students' comprehensive quality. Candidates need to study more, practice more and think more, in order to achieve ideal results in the college entrance examination and move towards the road to success.
