As far as the Chinese Academy of Sciences is concerned, there are four kinds of papers in mathematics besides national papers: advanced mathematics A, advanced mathematics B, advanced mathematics A and advanced mathematics B; Among them, the difficulty of high number A is equal to high number A, the difficulty of high number B is equal to high number B, and the difficulty of high number A is much higher than that of high number B; High numbers A and B are propositions of Chinese Academy of Sciences, and high numbers A and B are propositions of Chinese University of Science and Technology.
As far as the high number B of the proposition of the Chinese University of Science and Technology is concerned, the difficulty is lower than two, and the outline can be found on the website of the Chinese University of Science and Technology. The reference value of real questions over the years is quite high, especially in recent years; There is little change in the types of questions between adjacent years, so it is not necessary to go beyond the outline when reviewing, but almost all the exams are required by the outline. The knowledge points required by the outline are clear and clear, and the number is small, so it is easy to get high marks.
As for the reason why the number of questions changed little between adjacent years of high number B, my humble opinion is as follows: high number B is an independent proposition of colleges and universities, and it is often colleges (departments) that undertake the task of writing questions. The questions should not be difficult, biased, strange or undifferentiated, especially for universities like China University of Science and Technology, its influence should not be underestimated; But as far as an institution is concerned, it is impossible to have a perfect evaluation mechanism like the national volume. In order to keep the difficulty of the test questions stable, it is more appropriate to adopt an effective way, that is, the test questions between adjacent years should not be changed too much to ensure that the test papers will not make mistakes, but should be changed a little to adjust the difficulty and improve the test function of the test papers.
However, the change of question type does not mean that the question type is always simple. According to my feeling, there are several routine questions in high number B in 2008, which have a large amount of calculation and are easy to make mistakes.
I searched it online. I hope it helps you.
Counting one is more difficult than counting one, and counting one requires more test sites.
