However, from the point of view of examination alone, college entrance examination mathematics is much more difficult than postgraduate entrance examination mathematics.
In the college entrance examination, the content of mathematics is mainly elementary mathematics. Its knowledge points are very simple and easy to understand compared with postgraduate mathematics. As long as people with normal IQ can easily master all the knowledge points of elementary mathematics, there is nothing that normal people can't understand anyway. This is very difficult for the mathematics proposition group of the college entrance examination. If we only test the knowledge points, everyone will get a score of 90 or above (100 on a percentage basis). One of the biggest tasks of the college entrance examination, distinguishing people, can't be completed. Considering that everyone is above 90, 100, who is better? Therefore, there is only 1 way for the mathematics proposition group in the college entrance examination, that is, we should constantly work hard on the examination questions themselves, turn an examination question into many bends, make the examination questions like a maze, and make the candidates dizzy as much as possible, so as to distinguish who is less prone to dizziness. This is the cleverest. However, the candidates and the teachers in Grade Three are not stupid, so they spent 1 year without learning new knowledge, and practiced a lot of knowledge about how to quickly understand the maze and solve it around the exam questions. The proposition group can't do it at first sight, and the small maze can't bypass you. Let's have a bigger maze! So the maze is getting bigger and bigger, but in fact only those knowledge points have not increased at all. Just like playing the Rubik's Cube, the 3×3 Rubik's Cube has stumped everyone. They are all restored within 30 seconds, and the difference is only one or two seconds. A large number of people have the same result (if hundreds of thousands of people take the exam, if they are all restored within 30 seconds, the fastest is 25 seconds, think about how to distinguish). What should I do? Change into a 4 x 4 Rubik's Cube! Not yet? Add 5 x 5, 6 x 6 ... Finally, you can always tell who is slow and who is fast.
But in the postgraduate entrance examination, the content of mathematics is mainly advanced mathematics. There are too many contents and knowledge points in advanced mathematics, so it is a problem whether candidates can master all the knowledge points. Moreover, many knowledge points of advanced mathematics are very difficult to understand, and not anyone with normal IQ can master them. For example, many people just can't understand vectors and tensors (needless to argue, of course, many people can understand them). Therefore, it is a little easier for the postgraduate entrance examination mathematics proposition group than the college entrance examination mathematics proposition group. There are many knowledge points to be tested, and the knowledge points themselves are difficult. There is no need to bypass the examinee with a maze. Knowledge points themselves are difficult to climb. Therefore, the examination questions of the postgraduate mathematics itself will not be too curved. You can do it if you master the knowledge points, but you can't do it if you can't master them. Therefore, postgraduate mathematics is more like a level test such as IELTS English. If you reach the level, you will naturally get high marks. If you don't reach the level, you can't practice well.
So we can't simply evaluate which math exam is more difficult. We can only say that in order to distinguish the level of candidates, the mathematics proposition group of the college entrance examination is constantly spinning around simple knowledge points to see who can play fast; The mathematics proposition group for postgraduate entrance examination is to list the knowledge points with different difficulties and see who can climb up.
From the perspective of quality education and exam-oriented education, postgraduate mathematics is more like an exam of quality education, depending on your own level, while college entrance examination mathematics is purely an exam-oriented education, with a low degree of twists and turns. I didn't mean to criticize the college entrance examination. There is really no better way to select some elites from a group of ordinary people than the college entrance examination.
