First, consolidating basic knowledge is the premise.
Judging from the real math questions of the postgraduate entrance examination in the past ten years, 80% of the questions in the test paper are basic questions, and only a few partial questions and questions really need to be pondered. This requires students to thoroughly understand the basic concepts, methods and theorems in combination with the postgraduate counseling books and outlines. Only by deeply understanding the basic concepts and firmly remembering the basic theorems and formulas can we find the breakthrough and breakthrough point of solving problems. Mathematics needs to emphasize the basics rather than the skills. Many students often don't pay attention to basic learning, but are busy doing problems, trying to get high marks in postgraduate mathematics through sea tactics. Just like a child who can't walk, he always wants to run directly. Even if he put in more energy, of course, he can't achieve the expected effect.
Second, think more and do more questions.
Many students like to look at examples when studying mathematics, like to look at other people's good topics, and like to look at other people's analysis and summary of good problem-solving methods and steps. Just passively accept other people's things and never become your own. You must think for yourself when you do the problem. No matter how far you go, at least you have thought about it. Only in this way can we have a deeper understanding and mastery of knowledge and have the ability to solve problems independently.
