I m a junior high school student, and I m not good at math, physics and chemistry, so how can I impr

What exercises do you need to do more, especially the exercises in the book, you must understand it thoroughly, because the topics of the book have a certain foundation and are closely related to the knowledge points of the book. And you should have at least one class a day to learn mathematics, and review the knowledge points learned that day before starting to do the problems, and the same is true for chemistry, you must review the content of the day before starting to do the problems. It is best not to open the book to read the knowledge points when doing the questions, and immediately answer the questions after completing the questions, and then figure out the mistakes.

Don't focus on the difficult questions before the exam, review the knowledge points in the book first, and then look back to see if you understand the questions you did wrong.

Find the right review book, such as Dongfang Laser's high school entrance examination review tutorial, the knowledge points are well organized. However, the latter questions are not suitable for students with middle and lower grades. Do the final unified examination questions, one model, and two model questions in various districts of Shanghai for two years. In this way, the foundation will be solid.

First of all, don't worry, it's not something that can be seen overnight. If your mathematics, physics and chemistry are not good, then there is a lot of room for improvement. It is recommended to go to the bookstore to buy an exercise book that summarizes the classroom knowledge, and then memorize the basic knowledge points in combination with the textbook, and then do some exercises.

Gradually increase the number of exercises. In our Chinese-style education, the question sea tactic is a necessary way, because this way will allow you to master all the question types, and because the knowledge learned in junior high school is very limited, the questions are nothing more than some fixed question types. Gradually find self-confidence in doing the questions, and I believe that you will get smoother and smoother.

Improve your test scores, no shortcuts, study hard. The best way is to do more questions, practice repeatedly, practice makes perfect.

As long as you do a few sets of comprehensive workbooks in each subject, you should be able to master the basic knowledge, and for students who do not have a good foundation, you can improve your score a lot.

Of course, if the family conditions allow, it will be better to find a junior high school teacher to make up lessons one-on-one.

If I don't do well in math, physics, and chemistry in the third year of junior high school, is there a remedy? Answer: "Yes". Please see below the learning methods of physics and chemistry in the third mathematics of junior high school.

To improve academic performance, the key lies in the students themselves, first of all, hard work is necessary, secondly, to strengthen the collusion with the teachers, they have not fully mastered the knowledge points to ask the teachers in time, third, there are still 5 months before the high school entrance examination, and the mathematics, physics and chemistry of junior high school is not too difficult, to strengthen the knowledge points to summarize, do more types of questions, and the representative question types are sorted out separately, so that the review is handy, but also to expand the scope of knowledge, Don't engage in sea tactics, time is no longer allowed, and it has little effect.

1. Sort out the knowledge framework and clear the knowledge loopholes

The first step in learning any subject is to sort out the knowledge framework, the main purpose of which is to build your own knowledge system, and at the same time check the subject knowledge loopholes and fill in the gaps in time, clear the learning obstacles, and lay the foundation for future learning.

2. Lay a solid foundation and focus on basic knowledge (theorems and formulas).

Basic knowledge determines the upward space, and there are science subjects such as mathematics, physics and chemistry, whose knowledge is often interlocked, and if one link is dropped, then the latter will inevitably not be learned. Therefore, if you want to improve quickly, you must first consolidate the basic knowledge, memorize the theorem formula, and then carry out "actual combat".

3. Do more questions and do more questions

"Knowing by doing" often applies to all kinds of things, but it also applies to learning. Therefore, after mastering theorems and formulas, students should carry out "actual combat", and applying what they have learned is the foundation of learning. However, in the process of doing questions, avoid sea tactics, do more questions, but also do good questions.

For many junior high school students, the results of mathematics, physics and chemistry are not very ideal, because the difficulty of mathematics, physics and chemistry is relatively large, especially for girls, logical thinking is not good, and there will be many difficulties when studying.

1. Find all the textbooks of mathematics, physics and chemistry in junior high school, and then start with a simple plan in a planned way. In fact, when we go to the third year of junior high school, we will find that a lot of knowledge has become easier in the first and second years of junior high school, so it is very easy to review;

2. Write down all the knowledge points that you don't understand or can't drink or even don't understand well, find a way to ask teachers and classmates, try to understand all of them, and tick those you understand, so that you will find that there are fewer and fewer things you don't understand;

3. Perseverance, no learning is achieved at one touch, it is the result of long-term accumulation. Sort out your study plan and take it one step at a time. Teachers and parents can be invited to participate in the learning plan to play a supervisory role;

4. If the conditions are possible, find a tutor, one-on-one, and the performance improvement will be good, but the cost will also be very high;

5. The most important point is that all the theorems and formulas learned must be able to be used flexibly, and never memorize them. Accustomed to carefully reviewing the problem, you should find a way to transform the problem into your own ideas.

Learning mathematics cannot only be taught by teachers, but also by taking the initiative to understand and master it. Students should take the initiative to discover problems, pay attention to the internal connection between new and old knowledge, not be satisfied with ready-made ideas and conclusions, and often carry out exercises with multiple solutions and multiple changes in one question. It's not okay to just read books and don't do questions, and it's not okay to just bury your head in questions and not summarize and accumulate.

Students should not only be able to drill into the textbook knowledge, but also be able to jump out, and find the best learning method based on their own characteristics.

Children are not good at mathematics, physics and chemistry, in fact, there are two situations. First, I feel that I am not good enough. One is failing.

If it is not good enough, it is recommended to gnaw on the problem. Parents can help sort out the wrong questions, and those with higher ability can summarize that some of the wrong questions belong to the same type of knowledge points.

For students who fail, parents focus on their children's basic knowledge. A normal volume has a ratio of 7:2:

1. 70% are easy questions, 20% are medium difficult questions, and only 10% are difficult questions. If your child's foundation is not good, give up the most difficult 10% decisively and concentrate on sprinting for simple questions. I got as much as I could get it.

To improve academic performance, the key is still the students themselves, first of all, hard work is necessary, secondly, to strengthen the collusion with the teachers, they have not fully mastered the knowledge points to ask the teachers in time, third, there are still 5 months before the high school entrance examination, and the mathematics, physics and chemistry of junior high school is not too difficult, to strengthen the knowledge of the points of induction, do more types of questions, and the representative question types are sorted out separately, so that the review is handy, but also can expand the scope of knowledge, Don't engage in sea tactics, time is no longer allowed, and it has little effect.

Poor grades in the third year of junior high school mean that it is difficult to be admitted to high school, and you may only be able to go to vocational high school or technical secondary school after the high school entrance examination, and if you want to go to high school, you can only consider local private high schools or international high schools. Taking Beijing as an example, students with poor grades in the third year of junior high school in various districts of Beijing can apply for some private characteristic high schools (college entrance examinations) in advance, as well as more than 100 international high schools (international admission) in Beijing.

List of private characteristic high schools in Beijing that can sign a contract in advance (college entrance examination and study abroad):

1. Beijing Mingcheng Foreign Chinese School, Humboldt College, Small Language High School Program 2, Beijing Dongfanghong School, Mingde College, Roll Japanese High School.

3. Singapore Bilingual High School Program of Beijing Zhongguancun Foreign Chinese School 4. Beijing Huairou Solanno High School International High School Program.

5. College entrance examination class of Beijing Foreign Language Chinese School.

6. Tsinghua Zhiqing International Department Small Language High School Project.

List of high-quality private international high schools in Beijing (international further education):

1. Beijing Keystone School (Shunyi District).

2. BIBS School (Shunyi Tianzhu Campus).

3. Beijing Huijia International School (Changping District).

4. Beijing New Year Yu Yingcai School (Shunyi District).

5. Beijing Haijia Bilingual School (Shunyi District).

6. Beijing Royal School (Changping District).

7. Beijing Lecheng International School (Chaoyang District).

8. Beijing Aidi School (Chaoyang District.

9. Beijing World Youth International School (Chaoyang District).

10. Orange County International School (Beijing Campus) (Changping District).

11. Beijing Campus of Lingke Education (Haidian District).

You can also go to a technical secondary school to take the college entrance examination, and you must learn to improve your academic qualifications to improve yourself in order to have a good future!

The basic concepts should be clear, the basic laws should be familiar, and the basic methods should be proficient. The texts must be familiar and the knowledge points must be remembered clearly. At least the illustrations in the textbook have a clear impression in the mind, it is not necessary to remember how many sides, but at least know whether it is on the left or right page, what knowledge points it is about, what phenomena are demonstrated, what is the end of what is obtained, and can be extended and comprehended.

It is necessary to do some questions independently (meaning not relying on others) and with quality and quantity. There should be a certain number of questions, not too few, but also a certain quality, that is, a certain degree of difficulty. Anyone who learns mathematics, physics and chemistry will not be able to learn well without going through this level.

Solving problems independently, sometimes slowly, sometimes detours, sometimes even unable to solve them, but these are normal and the only way for any beginner to succeed. It will be fruitful to know the topics that you don't know and expand your knowledge and memorize them.

Practice doing comprehensive test papers, after finishing and analyzing the wrong questions, the analysis will find that the wrong questions often contain the same knowledge points, that is, the knowledge points are not firmly grasped, and the knowledge points are studied in a targeted manner and the relevant exercises are done to thoroughly grasp the knowledge points. This method is best suited for the revision and preparation phase. However, if you use this method in your daily study and don't bring the questions to the exam, I believe that the revision will be much easier.
