1 First, reflect on whether you recalculated yourself after the lecture.
Some people say why we need to recalculate, and I understand. Isn't this a waste of time? Actually, it's not. Because when we absorb other people's thoughts, we actually have absorption obstacles, so when we do the problem, especially when we encounter the original question and similar questions, there will always be a point stuck in the calculation process. So, you must clear your mind by yourself. Do the math yourself.
2. If it is a simple question, it is wrong. Then it's a matter of concept.
This may be a general statement. Reading class notes repeatedly may not be effective. It is better to understand a problem, a problem and a routine, and similar problems will have ideas. Brush the questions, but not all. Brush the questions you usually see, and then choose one or two to do the wrong questions. What topic should I choose? There are many ways to solve a problem, and there are several ways to solve a problem. If you master this problem, your mind will become more open. (The next time you encounter a question that you can't answer, turn over the handout, read a book, and read it with a purpose, your memory will be deeper. Then copy some formulas and handouts that you don't understand on the special page of the wrong topic book, where such questions are located. In this way, every time you make a mistake and encounter an unclear concept, you don't have to rummage around. Ps: I'm not asking you to copy everything. Only key formulas and concepts you don't understand should be copied. You don't have to write your own ideas when you do the problem. You can write if you want to be safe. )
3, well, going around and back to brushing the questions, although this sentence is very old and useful to many students, it may not be effective if you skim it.
There is indeed a problem of not brushing enough questions when doing the questions. But math is a routine. Let me teach you a stupid method, so to speak, because it really takes time.
Sub-topics (in terms of topics, it can be divided into big topics and small topics, which may be difficult to count. But in terms of big questions, you can browse the real questions of the college entrance examination in the past five years, not by doing it, but by seeing what it tests. )
Do the wrong question (the children of relatives have used it, and provide you with a small template. There are small problems ahead and big problems behind. You can also get a score of around 120, which is a little low, but at least you can get a basic score to get 130, 140. If your score is high, but you are not satisfied with the score of 120, 130 and strive for perfection, then you have to look at your test paper. The last chicken soup for the soul: as long as the college entrance examination is not over, everything is possible. Never give up!
