Hello, this is a common question that many students should say, I think.
(1) Read the question carefully. Many students are eager to answer questions in the exam, and want to write quickly to gain time. Often the result of time struggle is that the answers on paper can be said to be unrecognizable, and there are too many mistakes, mistakes and miscalculations. If these mistakes are avoided, the result will be "good".
(2) the training of problem-solving skills, we often only pay attention to the mastery of knowledge in our usual study, but don't care much about the training of problem-solving skills. In fact, the answers to many math problems can be obviously wrong, and multiple-choice questions and fill-in-the-blank questions also contain many skills. We should consciously train problem-solving skills in our usual study, and how can I test quickly and answer small questions quickly and accurately after calculation?
(3) Find the "taste" of the topic. In the formal examination, the difficulty of general questions is spiraling, that is, choosing, filling in the blanks and solving, from simple to difficult. Location determines their difficulty and calculation. If the simple question is "big", it means that your problem-solving tastes wrong. Don't do it blindly, think more. For example, the proportion of trigonometric functions in the college entrance examination is high, in the triangle ABC, SIN. . . Many students have developed sin(B-A), but there is no breakthrough after many calculations. That is, they haven't found the smell of the problem yet. It is impossible for a proposition to design the first line of a solution as a complex operation. After careful consideration, it is found that if the angle C is changed to 180-(B+A) by inductive formula, the two parts of the original formula can be combined and the taste is right.
(4) Students who are very thoughtful about the topic, most of whom do poorly in the exam, will be considered to have psychological problems. In fact, I think they have done a lot of questions below, but they don't know enough about them. They should always sum up the following questions and feel that there are fewer and fewer questions, that is, find some rules between them. If they find the same type of questions in the exam, they can answer them directly without thinking, reducing the possibility of making mistakes. After all, it takes 120 minutes, and it takes a lot of time and difficulty to use 150 minutes to do the topic. We can only relax and get ready.
Here are some answering skills:
There are some skills in multiple-choice questions. I'll give you a few tips. Due to the limited space, I will only give one example.
Clever guessing of (1) transformed image
(09 Beijing) Point P is on a straight line and y=x- 1. If a straight line passes through P, the parabola Y = X 2 is at points A and B, and PA=AB, then point P is called "point", then the following conclusion is correct (A).
A. All points on a straight line are "points"
Only a limited number of points on a straight line are "points"
C. All points on a straight line are not "points"
An infinite number of points (not all points) on a straight line are "points"
It is very difficult to solve this problem head-on, but if you draw a picture that is too observational, it is easy to find that A is correct.
(2) Maximum value method
(Haidian module 2) △ABC, a=csinA, and find the maximum value of (a+b)/c.
The simplest way to solve this problem is to add sine theorem to a=csinA, that is, sinC= 1, that is, C = 90, and directly guess the isosceles right triangle, (1+ 1)/ root number 2.
(3) Special value method
(09 country I) arithmetic progression, if S9=72, then a2+a4+a9=?
The essence of this problem is to examine the number and nature of three items, namely a2+a4+a9=3a5, which is difficult for many students to think of. However, if we think with special values, the sequence S9=72 satisfies the conditions, and a2+a4+a9 must be equal to 24.
(4) Exclude the sea
There are many examples of using option exclusion.
I hope you can have a good experience and use the exam flexibly.
In addition, every question in the general college entrance examination proposition is differentiated, that is, the proposer hopes that the score of this question is a step-by-step score. Some people get full marks, and some people get 10, 8, 6 and other scores, which can distinguish students of different grades. Therefore, even the last question, his entrance problem is often very simple. It is suggested that the first question must be carefully read before answering. If blocked, it is often an ideological mistake. Therefore, the first question of the big topic should be avoided, and the finale is often complicated deformation and ingenious structure, which is really difficult. Students are generally advised to answer as much as possible, because the future marking is a step to give points, and the steps will generally be good. In addition, there are actually some ... >>
How can I get high marks in mathematics?
way
1, the habit of "listening" seriously.
In order to synchronize teaching and learning, teachers require students to concentrate their thoughts in class, listen attentively to the teacher's lectures, listen carefully to the students' speeches, grasp the key points, difficulties and doubts, think while listening, and encourage middle and advanced students to take notes while listening.
2. The habit of positive "thinking".
It is an important guarantee to improve the quality and efficiency of learning to actively think about the questions raised by teachers and classmates and keep yourself in teaching activities. Students' thinking and answering questions are generally required to be well-founded, organized and logical. With the growth of age, we should gradually infiltrate mathematical ideas such as association, hypothesis and transformation when thinking about problems, and constantly improve the quality and speed of thinking about problems.
3. The habit of "taking exams" seriously.
The ability to examine questions is the comprehensive embodiment of students' various abilities. Teachers should ask students to read the content of the textbook carefully, learn to master the words and correctly understand the content, carefully scrutinize and ponder the key contents such as tips, marginal notes, formulas, rules, charts and so on, and accurately grasp the connotation and extension of each knowledge point. It is suggested that teachers often carry out special training of "the difference between one word and ten thousand words" to continuously enhance the profoundness and criticism of students' thinking.
4. The habit of "doing" independently.
Practice is an important part and natural continuation of teaching activities, the most basic and frequent independent learning practice of students, and the main way to reflect students' learning situation. Teachers should educate students not to blindly follow the viewpoint of eugenics in their understanding of knowledge, not to be influenced by others, and to easily change their own viewpoints; The use of knowledge does not copy other people's ready-made answers; After-school homework should be completed in good quality, quantity, time and neatly, and the best method should be achieved, and mistakes must be corrected.
5. Be good at asking questions.
As the saying goes, "curious children will become great people." Teachers should actively encourage students to question and ask difficult questions, ask teachers, classmates and parents with knowledge doubts, and strongly encourage students to design their own math problems and communicate with others boldly and actively. This can not only harmonize the relationship between teachers and students, enhance the friendship between students, but also gradually improve students' communication and expression skills.

How to get high marks in mathematics for senior high school entrance examination
First, pay close attention to the foundation, second, draw inferences from others, and third, practice repeatedly to test instead of practice; Specifically, first of all, we should concentrate on 12 points in class. Listen and practice more in every class, often practice with a pen, often think after class, review and consolidate, summarize the comprehensive questions and master the law of solving problems. As the entrance examination approaches, simulation training is essential.
What is the total score of college entrance examination mathematics? How can I get high marks?
The total score 150 is higher in first-class schools and higher in second-class schools. If you want to get high marks, you should generally do it: 1. You really need to listen carefully and take more notes in class, so it will be much easier after class. You can't stop practicing, you must stick to it and you will learn it well. If you don't understand, you must think about it first, and try to help others for at least half an hour. In the process of explaining to others, it means that you have a deeper understanding and discuss more with others. Solving more problems is very helpful for future study. 4. Conclusion If you can push the formula yourself, you can push it yourself after learning a formula, which will deepen your understanding and help you understand it. You don't have to memorize it, so you can use it flexibly through this process. There are not many questions, but we must think and do it ourselves, not for speed, for quality, and learn more from it. Almost.
How to get high marks in Chinese mathematics
Identity tells self-taught college entrance examination teachers to believe in some remedial classes.
Normal college students are coping with the college entrance examination. I am willing to listen to the teacher's complete adolescent rebellion. The teacher said that reaction is more important than drowning and being too familiar with water. The teacher said it was too frequent, and it was tiring to be distracted.
When I was in senior three, I spent most of my time waiting for the college entrance examination. I really believe I asked if the school had finished the exam and graduated.
Efforts besides listening to the teacher's instructions.
These experiences are only applicable to math and Chinese subjects.
