20 15 It's relatively simple to take the entrance examination for Mathematics II. 20 15 got a lot of high marks in mathematics for postgraduate entrance examination, and the topic was relatively simple.
Math II: Exam Content
A. Advanced mathematics (function, limit, unary function calculus, ordinary differential equation).
B linear algebra (matrix, matrix, vector, linear equations, eigenvalues and eigenvectors of matrices).
2. Postgraduate Mathematics 20 16
The mathematics of 20 16 is more difficult than that of 20 15, and the difficulty coefficient of 20 14 is basically the same.
The difficulty coefficient of ranking first is higher. Counting two is particularly difficult. The difficulty coefficient of number three is moderate.
The difficulty coefficient of Math II is particularly high, which is seriously higher than 20 14. About 40 points are rare sub-topics or off-topic questions.
(1) Question 5: Curvature problem: Most students can't remember the formula. (4 points)
(2) Question12: The equivalent order reduction method of Y-type differential equation is very skillful, which may surprise students. (4 points)
(3) Question 16: The interval additivity of definite integral is hard to think of. (5 points)
(4) Question 20: It is a digression to investigate the "star line" graph, and you must know the graph (1 1).
3. Graduate Mathematics II 20 17
Generally speaking, it is relatively simple, but some topics are easy to get stuck, with a slightly large amount of calculation and easy to be careless.
The difficulty of the big questions is almost the same, and the choice of fill-in-the-blank questions is indeed about 20 minutes simpler than in previous years. I didn't take the polar coordinate integral because I took it a few years ago.
Linear algebra is a routine problem, and if it is proved, the first small problem doesn't seem very difficult. Do the problem quickly, and there is also 140+.
4. Graduate Mathematics II 20 18
20 18 it is difficult to take the postgraduate entrance examination for mathematics.
Compared with 20 17, the number two is more difficult, and the amount of calculation is as large as ever. It is a test of students' computing ability and requires students to grasp the time during training.
5. Graduate Mathematics II 20 19
The sample size of Math II is 137200, and the difficulty coefficient is 0.40 1, and the actual situation may be less than 0.4. Therefore, when the sample size increases, the difficulty coefficient of 0.5-0.55 is the most reasonable, and it is more difficult below 0.5, and it is too difficult when the difficulty coefficient is 0.4.
Only twice in the past 20 years, the average scores of 20 16 and 20 18, and 20 18 hit a new low in the past 20 years.
6. Postgraduate Mathematics II 2020
The difficulty is moderate, and it is really difficult to calculate. The big problem is basically simple and routine, while the big problem of linear algebra is a bit difficult.
It is easy to appear that it seems simple and impossible. The calculation is troublesome and the result is messy. The simulation questions of the following 1000 answers are similar.
7. Postgraduate Mathematics II 202 1
202 1 Postgraduate Mathematics is based on the foundation. The topic is not difficult, but it is not easy to calculate.
This is the same as many students feel. You can get the problem at first sight, which is familiar and simple, but it is not as easy to do as you think. Perhaps it is because of the mathematics reform of the postgraduate entrance examination in 20021that the proposition teacher considers making as many students as possible familiar with and adapt to the reformed topics and questions, so the difficulty is slightly reduced.
8. Postgraduate Mathematics II 2022
There are too many conceptual questions to choose, and many options are uncertain when they are done. The calculation of fill-in-the-blank questions is a bit large. The number two-choice questions are very new, and filling in the blanks and big questions are mostly routines.
As long as you do the real questions, you will find that the math problems in 2022 are very similar to those in 2020. It's just that the math of 202 1 is too simple, which makes many candidates relax their vigilance.
