The college entrance examination in 2022 has ended. This year’s mathematics paper is considered to be very difficult by many candidates. Some netizens broke the news that Peking University Mathematics Wei Shen also commented on this year’s mathematics paper, saying that a score of 140 is still very easy.

Wei Shen’s thoughts on this year’s math volume:
This time the college entrance examination is okay, let’s take mathematics as an example, the derivative problem is solved directly by Lagrange’s mean value theorem and the Taylor formula of Peano’s remainder!
The problem of analytic geometry is only to find the curve integral on the ellipse, and then to find the double integral in the area covered by the ellipse is OK. The solid geometry is even simpler, and the triple integral package is directly included.
Let’s talk about the question of the sequence. First, use Dirichlet’s sufficient conditions to prove that the general term formula converges to half of the sum of the left limit and the right limit at the discontinuous point, then perform Fourier transform, and use the Laplace equation to find the N order derivative. And, finally take a limit just fine.
Probability questions that you can get right with your eyes closed? In this way, all major questions have been solved. The previous questions are all score-giving questions, and you are also allowed to make mistakes. It is still very easy to get a score of 140.
However, the comments of Wei Shen on the Internet have not been confirmed.Considering the previous Oolong incident in which Wei Shen solved the problems that plagued 6 doctors for 4 months in one day, this time Wei Shen commented on the mathematics volume may also be a joke sent by netizens.
Of course, in terms of the ability of Wei Shen’s Olympic math champion, it is not a problem to score 140 in the mathematics test of the college entrance examination. This statement is not an exaggeration.
Regarding the difficulty of mathematics, Chen Zhiwen, an expert from the National Education Examination Steering Committee, emphasized that the difficulty of the college entrance examination proposition does not affect the admission of high school, nor does it affect the fairness of education.
He added: The score line is essentially a ranking line that is finally determined according to the number of applicants for the college entrance examination. If everyone performs well, the score line will “raise the boat”; if everyone does not perform well, the score line will be low, and candidates and parents need not be anxious.
