That is to say, from the first year of the unified mathematics examination, one of the characteristics of the postgraduate mathematics proposition is that the latest proposition will appear ideas or angles that were tested more than ten years ago or even more than twenty years ago, especially linear algebra.

For example, the second largest problem of linear algebra in 2020 is very difficult and unconventional for many students, as if it had never been done. If you study the real question carefully, you will find that this idea has already appeared in the test of 200 1, and there are many similar examples.

If you encounter a difficult problem, it's really chewy. A clever strategy to solve a problem is to break it down into a series of steps or small problems. Solve some problems first, solve as many as you can, and write as many steps as you can. Failure does not mean failure.

Especially those problems with obvious problem-solving level, or procedural methods, can score every step of calculus. Although the final conclusion has not been reached, the score is over half. It's called "getting points for big questions", which is really a good idea. Postgraduate mathematics, postgraduate subjects.

According to the different requirements of various disciplines and majors on the mathematics knowledge and ability that graduate students should possess, there are three kinds of mathematics papers for graduate entrance examination, and the types of papers used by different majors have specific provisions.

The main differences between one, two and three in mathematics for postgraduate entrance examination

The main difference between the first, second and third postgraduate mathematics lies in the different test objects and different test contents. One is for students who apply for science and engineering, and the examination contents include advanced mathematics, linear algebra, probability theory and mathematical statistics; Mathematics is an examination for students who apply for agronomy, and the contents of the examination are only advanced mathematics and linear algebra; Math 3 is an exam for students who apply for economics. The contents of the examination are advanced mathematics, linear algebra and probability statistics.

Problem-solving skills

In the improvement stage, we first classify the real questions according to the types of questions, and start with the types of questions to do the real questions. This has two purposes. First, you can know how far you are from the exam. Secondly, when we do different kinds of real questions, we can also know where our knowledge is relatively weak, which is convenient for us to check and fill in the gaps and do special review.
