Since the merger of Mathematics (3) and Mathematics (4), there has been no new change in the mathematics syllabus for postgraduate entrance examination. However, the syllabus of 202 1 postgraduate entrance examination has changed a lot, which also makes mathematics stand directly in the C position of the syllabus change. Not only the content and requirements of the test center have changed, but also the number and scores of each type of test paper have been greatly adjusted.
1, the proportion of each subject in the test paper and the adjustment of the question score.
(1) Count the changes of Kobe's weight in the first, second and third papers.
(2) Changes in the number of questions and scores of each question type.
The total number of mathematics questions changed from the previous 23 questions to 22 questions, among which multiple-choice questions increased to 10, and each question scored 5 points. The number of fill-in-the-blank questions has not changed, but the score of each question has increased to 5, the total score of the solution question has decreased to 70, and the number of questions has also decreased to 6.
Note: ① With the increase of the number of objective questions, the score also increased to 5 points per question. This shows that the increase of multiple-choice questions requires higher basic skills for candidates. The multiple-choice questions in mathematics have only two scores of 0 and 5, and the multiple-choice questions in each question are very important. There were many questions to answer before, even if everyone's calculation results were wrong, there would be process scores. However, after a large proportion of multiple-choice questions, it is more difficult to grade, which also requires students' computing ability and understanding of various concepts.
Although the number of fill-in-the-blank questions has not changed, the score has increased to 5 points per question. This requires everyone to have higher requirements for the accuracy of calculation and the importance of results.
(3) The small number of answers to questions is not a good thing for candidates. This means that the comprehensiveness of the exam will be improved and the computational complexity will increase. The propositional point of the solution will move back.
2. Changes in the content and requirements of test sites
? This year, the content of the test center has not been deleted, only increased. Next, let's take a look at the specific changes in the content of the test sites on the first, second and third.
(1) Mathematics 1: the comparative discrimination method of improper integral increasing improper integral convergence and divergence, and the discrimination method of infinite series increasing integral.
⑵ Math 2: improper integral's comparative judgment method of increasing improper integral's convergence and divergence, and double integral increasing double integral mean value theorem.
⑶ Math III: improper integral comparison discrimination method, Cauchy discrimination method and integral discrimination method for increasing improper integral's convergence and divergence.
? In short, the requirements for test sites, the refinement of content, the improvement of test level, differences and difficulties tend to be balanced.
