Generally speaking, eight years of mathematics is getting easier and harder year by year, just like riding a roller coaster.

/20 15 postgraduate entrance examination (easy): the difficulty is very mild, and there are many things that return to the original, and even the derivative quotient law in the textbook is tested to prove such a problem.

/20 16 Postgraduate Entrance Examination (difficult, almost the most difficult in history): It gave a blow to a considerable number of candidates, completely different questions and huge calculation, which made many candidates collapse directly after the exam.

/20 17 Postgraduate Entrance Examination (Easy): The overall difficulty returns to a level of peace, and only a few questions reflect the level of mathematical thinking, so as to reflect the degree of discrimination.

/20 18 postgraduate entrance examination (difficult): It's quite bleak again (especially Math II and Math III). Many candidates are complaining, but the difficulty is lower than that.

20 16 postgraduate entrance examination, because there are many new routines in 20 16 postgraduate entrance examination, which can't be found in previous years, and there are various traps, but

There are almost no new routines in the 20 18 postgraduate entrance examination, and many questions are quite familiar at first glance.

/20 19 Postgraduate Entrance Examination (Easy): The overall difficulty is moderate and easy, which is significantly lower than that of 20 18, especially in mathematics.

/2020 Postgraduate Entrance Examination (difficult): There are no super-class or unpopular test sites in the whole volume, and there is no intentional cumulative calculation (obviously, the line is used instead of the second order to deliberately reduce the calculation of the whole volume).

However, many subjective questions in the part of high numbers and probability modify the proposition angle of familiar test sites, which makes many candidates feel both familiar and unfamiliar, that is, they can't find the direction of solving problems, or they can't find the direction of solving problems immediately, which requires many trial and error, thus wasting a lot of time.

This is the main performance of the mathematics difficulty of the 2020 postgraduate entrance examination.

/202 1 Postgraduate Entrance Examination (Easy): It is the first exam after the outline changes. There are many conceptual questions, no partial questions or strange questions, only a few difficult questions, and the difficulty of the test paper is much lower than that of the 2020 postgraduate entrance examination. On the whole, the exam didn't really reflect the intention of the new syllabus.

/2022 Postgraduate Entrance Examination (difficulty): The overall difficulty is a little higher than that of 202 1 Postgraduate Entrance Examination (the difficulty of multiple-choice questions is moderate, and the comprehensive degree of subjective questions is slightly improved), but it does not reach the difficulty level of even years in previous years. The main features are as follows: first, the foundation is the mainstay, and the examination methods of real questions in previous years are repeated more; Second, the amount of calculation has increased.

Odd years are easier than even years. According to this trend, the mathematics difficulty of the postgraduate entrance examination in 2023 will be reduced, but not too much. So, how to deal with the 2023 postgraduate mathematics? Xiaowa suggested at least the following three points:

/1. attaches great importance to the training of computing ability, including computing accuracy and computing speed. Fast and accurate calculation is a basic skill, and you should practice it every day (you don't need to spend a lot of time practicing it every day, just practice 10 questions every day), and you should run through the whole review process without relaxing for a moment.

It is ideal to practice conditioned reflex and know how to deal with it without thinking. However, it should be noted that training computing ability is not hard work.

Taking the double integral titles of 202 1 and 2022 as examples, 202 1 can be simplified by changing the order, and 2022 can be simplified by adding auxiliary lines, which shows that it still reflects the degree of distinction in calculation. In other words, if you have strong thinking ability and can calmly analyze, you can find a better method, which is both time-saving and accurate. This is the degree of differentiation of postgraduate entrance examination.

/2. Do the problem completely independently, standardize the problem (based on the actual test, do it in an orderly manner, without skipping or scribbling), summarize the right and wrong problems and the problems that can't be done, including analyzing the reasons for doing the wrong or impossible, writing the key breakthrough points (key steps), analyzing the angle of doing the problem, and trying to find a more concise and clear method of doing the problem.

/3. Master the corner (unpopular) knowledge points that have not been tested for many years or are not frequently tested, because the appearance rate of corner (unpopular) knowledge points in objective questions will increase under the new test paper structure after the outline changes.
