How to get a high score in mathematics, physics and chemistry in high school, give some specific adv

First of all, we said that the college entrance examination now attaches more importance to the three bases, and the question setting is about 7:2:1 ratio. From this point of view, mastering basic knowledge, basic skills, and basic methods can get more than 70% points.

Secondly, the college entrance examination is done under high pressure, and the degree of discrimination is high, at least to a certain extent. Only by strengthening training can students have the corresponding problem-solving ability. Numeracy skills take a lot of practice to improve.

The ratio of easy, medium and difficult test questions is generally 4:4:2, master the basic knowledge, and then be more serious, the easy part can get all, if you work harder, plus luck, you can get 2-3 in the part of 4, so that you can get 60%-70% of the score of the college entrance examination, if you calculate according to the standard of Beijing (full score of 750), you can get 450-525 points.

The college entrance examination proposition only has a textbook when proposing a proposition, so almost all the knowledge points of the college entrance examination questions can be found in the textbook, and there are just a lot of changes, but no matter how they change, they can't get out of the textbook, otherwise it will be considered that the proposition is beyond the outline, and the proposition person will bear a huge responsibility.

So it's not a problem, it's a matter of how well you master. Those who are proficient can go to Tsinghua University and Peking University, and those who are not skilled in junior colleges may not be able to go to them.

The ratio of easy, medium and difficult test questions is generally 4:4:2, master the basic knowledge, and then be more serious, the easy part can get all, if you work harder, plus luck, you can get 2-3 in the part of 4, so that you can get 60%-70% of the score of the college entrance examination, if you calculate according to the standard of Beijing (full score of 750), you can get 450-525 points.

Theoretically, 80% is the foundation of the test, so it should be 750*80%=600

1. Chemistry requires many aspects of ability: memory of fragmented knowledge, number crunching, descriptiveness, inference and analysis from known information, etc. However, the ability requirements in these aspects are not high, in terms of the richness and fragmentation of knowledge content, chemistry is much smaller than biology, and in terms of the amount of calculation and analysis difficulty, chemistry is also lower than physics and mathematics.

2. Therefore, as long as your ability is relatively balanced, chemistry questions will not become the biggest obstacle. On the contrary, if you are very poor at one area, chemistry questions that test that area will give you a headache.

3. Learning chemistry is really changing your knowledge system, and the changes in this balance and matching want to change from two-dimensional to three-dimensional, and then you can suddenly look at everything you have learned from a higher perspective.

4. For example, the concept of acid and base, for example, metathesis reaction: when I was in junior high school, the teacher told you that the metathesis reaction generates insoluble matter, water, and gas, and the teacher told you that in fact, the generation is non-electrolyte, and then you will find that the generation is a substance with a smaller solubility product, not necessarily a non-electrolyte, and the reaction principle is that the energy of the system should be lower, so that the system is stable.

5. In the study of chemistry, the first method is to accurately grasp each concept, summarize some counterexamples that are often encountered, and combine the two with each other. For example, if there is a non-metal, it must be a covalent compound, then it will be found that ammonium chloride refers to an ionic compound composed of non-metals.

In this way, the concept of covalent compounds can be fully grasped. The second point of the question, you can write the steps you take next to the test questions, whether it is chemistry or mathematics or physics, so that you can really know the reason for your mistakes when correcting, and at the same time, you can also correct yourself little by little Some bad habits and improve your scoring efficiency.

Personally, I think that the solid geometry of high school mathematics is indeed more difficult than that of junior high school and elementary school. Trigonometric functions are new to the knowledge, as long as students master the steps of solving problems in the learning process and memorize a large number of formulas for solving problems, the difficulty of solving trigonometric functions is not very high. The next two types of questions are permutations and combinations and sequences, and there are not many types of questions, but students need to memorize small ways to solve each question type.

Learning math may seem very difficult, but there are many tricks involved. As long as students fully understand some of the difficult points of mathematics knowledge, plus do problems to consolidate knowledge points, and improve mathematics scores, it is like a fish getting water.

Whether it is a small example geometry problem to solve, or a complex geometric problem and derivation that is difficult to solve, Xueba often takes a very simple approach. In fact, on the other hand, there are many types of math questions in the college entrance examination English, although the question types are constantly changing, but the knowledge points involved do not change very much. At the same time, students can use part of their extracurricular knowledge to consolidate their previous knowledge points, and finally achieve the goal of falling through the water.

After entering the third round of review, the teacher no longer forces students to do new questions, but hopes that children will try to do example problems from previous years. The main reason is that the types of mathematics questions in past past questions are more classic, and people can summarize the law of question type changes through the example questions of the college entrance examination in the past ten years. When students grasp the law of question type changes, the knowledge points in their minds are applied to the problem solving steps, and finally the perfect solution effect is presented.

In general, students should build confidence in overcoming difficulties when learning high school mathematics. If students are faced with a difficult math problem in the first year of junior high school, they will have the idea of giving up. Even if the knowledge points in the later stage focus on accumulation and application, and the consolidation of knowledge and knowledge accumulation services in the early stage are in place, students will not be able to successfully improve their college entrance examination scores.

Please believe in your mathematical prowess, and you can also become a dark horse in the college entrance examination.

Practice more questions, the basic knowledge must be mastered, in order to improve the score, high school mathematics is really difficult.

If you want to focus on the wrong questions and the questions you don't know, you can sort out the wrong question book, and you can apply for a math cram school; High school math is really hard.

It is not difficult for an ordinary person to improve his score in high school math. If you want to improve your math scores, you must first spend a lot of time to make up all the basic knowledge points, and the second time is to conduct special training for some key and difficult points; As long as you spend enough time and ask a classmate who is better than you to teach you, you will be able to improve your grades in the end. <>

For many people, high school math is a headache subject, after all, high school math itself is not as simple as we think. Although the knowledge points of high school mathematics are just a little bit, but because everyone's proficiency is very high, the form of the questions is ever-changing, coupled with the authorities, if you are in the study of mathematics, you often ignore the mastery of some key and difficult points, and finally the high school mathematics results are not satisfactory.

1. First and foremost: Spend a lot of time on the basics <>

In fact, it is necessary to spend a lot of time on math tuition, and the learning of basic knowledge is particularly important. The basic knowledge basically accounts for about 90 points in a math paper, which means that the basic knowledge is solid, and the last 150 points of the paper will have 90 points. Since the basic knowledge points are relatively simple and scattered, this nuclear mask requires us to spend a lot of time to tutor, which is also very necessary.

Secondary: Spend time every day for special training <>

After the basic knowledge is improved, we probably have about 90 points in the volume, at this time, we can make up for the key questions after the next 20 questions, because the last questions are basically the combination of derivatives and functions, this kind of questions have higher requirements for personal basic knowledge. On the basis of what we just said, we can ask some teachers or stronger students to teach ourselves, after all, sometimes it is very important for students to communicate with each other, and we can ask other students with a more humble attitude, which can help improve our social relationships and improve the focus of difficult points.

First of all, you must be very familiar with the basic knowledge in the textbook and understand the filial piety, in addition, you should write all the problems after class, and do all of them, and usually do the wrong questions should also be sorted out on a wrong board, fixed to review, buy more exercise books on the market, can let you understand the solution ideas of each type of math problem, do more questions, your natural math score will be raised; High school math is very simple, and if you are willing to work hard, you will be able to improve your grades.

Practice more questions, the basic knowledge must be mastered, so that you can better improve your score, high school mathematics is indeed more difficult.

Do a good job, that is, the choice and fill in the blanks in front, I don't know how many questions you have in your province, but generally the last two are the most difficult, so first tackle the front of the big questions, the back two will do the first or two questions and small questions, you can get points, at least take step points, but this is to ensure that you still have time on the basis of the absolute front, and then want to take step points. If the foundation is not firm, the ground will shake. Understand all the basics, take the time to review the book from the beginning again, and ask the teacher often if you don't understand.

Generally, the more difficult questions appear in Choice 10, Fill in the Blanks 5 and the last two big questions, grasp the time well and don't spend time on tackling tough problems.

In addition, your basic knowledge is not firm, and it is very difficult to improve quickly, because you are still a sophomore in high school, so there is enough time, don't worry, the foundation is very important in the college entrance examination, work steadily, don't look at other people's results, look at your own longitudinal development, so that you will have confidence. In addition, don't worry too much, one of my classmates was like you, a year to fight over, she is now at Xiamen University, come on!

1.Before you get the paper, take 2 minutes to go through the entire test paper so that you know what to expect.

2.Choose fill-in-the-blank questions to keep track of the time, and write the question number when typing the draft to make it easy to check, of course, there is generally no time to check. If you don't do your last math question completely, don't waste time and go back and check the answers to the multiple-choice fill-in-the-blank questions.

3.The questions are generally presented in the order of trigonometric sequences, solid geometry, probability, analytic geometry, limits, and elective questions. However, you can adjust the order of the questions according to the difficulty of the questions themselves.

For example, after doing the trigonometric function or number series problem, and then doing the solid geometry, you find that the second question is more difficult to do, you can spend 5 minutes thinking, but you should know that the exam time waits for no one, if you can't do it all the time, I recommend that you do the elective or probability questions first (depending on the difficulty of the question or the type of question you are good at). After doing the elective questions or probability questions, you still can't do the second question of solid geometry, don't be nervous, keep doing it.

4.Don't keep stumbling on one question, or you'll easily get nervous due to lack of time, which will make you more likely to make mistakes.

5.Pay attention to the details, and don't jump too much in the big questions, otherwise you will be deducted points.

6.In short, there will always be some tricky questions on the math test paper, which require more ingenious methods to do. And you need to give yourself the maximum score you can get in a limited amount of time.

Therefore, you need to make sure that you have a high rate of correctness and that you have enough time to complete the questions you will do.

Let me tell you about my real high school life, my math was very average in my first year of high school, I actively studied after the second year of high school, and at the request of the teacher, I used the math textbooks and textbooks I had learned to read through more than three sides in the after-class time, this process was very slow, and it tested people's patience, but my dream overcame my laziness, and I persevered. In addition, I can memorize almost all the example problems in the math textbook, which is very important because it helps you understand the meaning of the questions, grasp the ideas of solving the problems, and become familiar with the methods of solving the problems. Later, after the third year of high school, I took a lot of time to do exercises, at that time I had a book similar to the Han dictionary, I did it every day, the time was in the evening self-study, no matter what, I couldn't interrupt this habit.

In this way, with my persistent efforts, my college entrance examination score has made a breakthrough improvement. The score was 120+, but it was enough to surprise me because my math foundation was not very good. That's my real experience and I hope it helps.

Let me summarize it for you:

1. Read through the mathematics textbooks and textbooks on both sides, and be sure to be familiar with the textbooks.

2. Memorize the typical example problems on mathematics textbooks and important teaching materials, this step is very important, which will help to open up the idea of disintegration and clarify the perspective of the person who wrote the problem.

3. Do a lot of problems, don't believe other people's nonsense, how can you master the rules of solving math problems without doing too many problems? To hell with quality education! At that time, I thought to myself: I'm stupid, I can only improve my score like this, and I believe in my hard work.

I don't know what region you are in, if it is Liaoning or the new curriculum standard area, the following suggestions may be useful.

Mathematics is not as fast as science comprehensive mathematics is accumulated from junior high school or even elementary school Learn mathematics well The foundation is very important If your junior high school foundation is okay, then you should be able to improve to 120, and it may be higher, because after all, time is limited, conic curves and finale questions need more than a month of training to feel These 24 points, you can get 8 points, and choose to fill in the blanks, and strive to be all right, so that you can get 80 The first three big questions should be full of 36 points, and you should get 10 points for optional questions, so that your mathematics can be around 130.

At this stage, it is recommended to do a lot of mathematical objective problems, practice speed and accuracy, as well as multiple-choice skills, and at the same time, the foundation is weak, and it is necessary to check and fill in the gaps when doing the problems, including complex number calculations, transformation of trigonometric functions, sine and cosine theorem, basic elementary functions, basic theorems of space geometry, geometric properties of conic curves, permutations and combinations, and binomial distributions. If you miss it, you can see which one to pick the one that can improve the score first The most important thing is to have a firm belief Clear goal Believe in yourself to create miracles The most versatile way is to be down-to-earth! I wish you all the best in the college entrance examination.
