It is not difficult to go against the sky. 2 1 has no proof problem, which is simpler than 20 and more difficult than 19. After the exam, many people said it was easy, but many people were too arrogant because there were many traps. After all, the average math score is almost the same every year. Many people who shout simplicity may just not notice the trap itself. It is more important for individuals to lay a good foundation, and the preparation for postgraduate mathematics should return to the most basic understanding of knowledge concepts. Don't try to get started quickly.

In the future, the difficulty of mathematics for postgraduate entrance examination should no longer be as simple as 17. Don't practice too many dazzling skill problems that look wonderful. If you have a good foundation, a thorough understanding, and do normal questions, 100+ is not a problem. If you practice some questions that require active thinking or more knowledge, you will get high marks.
