The mathematical difficulty of the national college entrance examination is different in different areas of the national A-volume and the national B-volume, so it is not easy to quantitatively analyze the change of the difficulty of the test paper. Judging from the candidates' feedback, the difficulty of volume B in China has risen steadily. About 70% of the questions in the test paper examine the basic knowledge, and 30% of the questions need in-depth thinking and analysis. Generally speaking, propositions are abstract and require a large amount of calculation. The setting of mathematics test questions in Grade A national college entrance examination is quite satisfactory, but the setting of individual test questions is rather tricky and the angle of setting questions is very novel, and the overall difficulty is the same as in previous years. The first and second volumes of the new curriculum standard involve eight provinces. Before the college entrance examination, these eight provinces jointly held the mock exam of "Eight Provinces Joint Examination". During the "Eight Provinces Joint Examination", some candidates said that the examination was much more difficult than usual. However, after the math test of the college entrance examination, some candidates think that the difficulty of the college entrance examination paper is not under the mock exam. If this is really the case, it is indeed a bit difficult to mark the new curriculum. However, considering many factors such as the presence status, the subjective feelings of candidates are not necessarily accurate. Compared with the first volume of the new curriculum standard, the difficulty of the second volume of the new curriculum standard may be slightly less, because under the topic of mathematics in the college entrance examination, the candidates in the second volume of the new curriculum standard think that the difficulty of the college entrance examination paper is not much different from that of the usual mock examination. In addition to the above sets of papers, Beijing, Zhejiang and other places are separate propositions. If you don't see the ideas of the relevant candidates under the topic, you will not comment for the time being.
