Why do you forget to learn a lot of mathematics, physics and chemistry in the third year of junior h

Back then, in my second and third grades of junior high school, I never listened to classes, and my exams never fell below 95!

From my personal experience, understanding is important! Every concept, every theorem, every "general formula" must be understood! In the specific test questions, each parameter is different, this should be noted! Pay attention to the method, summative learning!

1. Memory is divided into two categories: first, the brain is born with a good brain and is unforgettable, and there are very few such people; Second, it is best to apply what you have learned and apply what you have learned in life.

2. When it comes to surfing the Internet, I don't know how your time is allocated, it is okay to use the Internet appropriately, but if you use too much time, your energy is undoubtedly not enough to learn the knowledge in class, and your memory will inevitably fade after a long time, I ask you a question: When you went to school when you were a child, you accidentally touched your arm, which year, month, and day?

1.Science in junior high school does not depend on whether you are smart or not, but whether you listen carefully in class, if you listen carefully, it is no problem to go home and do your homework, and then it is to review and consolidate, don't forget, and then use a variety of problem-solving methods, don't be lazy, use three or four methods to do a question, do more. This way you can think faster.

2.And then it is, if you tutor, don't think that the tutor is omnipotent, not the tutor will do the topic you will do, you will do it, (this is my experience as a tutor), all topics must use time to think about themselves, don't think about some in class, distraction is the most fatal point of middle school students, there may be dozens of seconds, the teacher said the solution to a problem, and the person who is poor will not at all, some students will not be able to, will not ask, so a little bit, the bigger the gapIn short, if you don't understand, you have to ask, and no one knows if you understand it in your heart.

The examination of mathematics is mainly based on the basics, and the difficult problems are only synthesized on the basis of simple problems. Therefore, the content in the textbook is very important, if the knowledge in the textbook cannot be mastered, there is no capital to touch the class.

1. For the content in the textbook, it is best to preview it before class, and the targeted practice questions after class must be done carefully, not lazy, and you can also repeat the class example problems several times when reviewing after class, after all, take good class notes when you are in class. "A good memory is better than a pen". For the solution of mathematical, physical and chemical problems, it is not enough to rely on the general idea in the head, but only after careful pen calculation can we find the difficulties and master the solution method, and finally get the correct calculation results.

2. Secondly, we should be good at summarizing and classifying, looking for commonalities and connections between different question types and different knowledge points, and systematizing the knowledge we have learned.

3. Finally, it is necessary to strengthen after-class practice, in addition to homework, find a good reference book, and try to do as many practice questions as possible in the book (especially comprehensive questions and application questions). Practice makes perfect, so that you can consolidate the effect of classroom learning and make your problem solving faster and faster.

4. It is inevitable to make mistakes in the learning process, whether you are careless or just not, you must habitually collect these wrong questions, and each subject has an independent set of mistakes, when we review before the exam, they are the key review objects, so since you miss once, you may not be wrong a second time, only in this way you will not lose points again on the same issue.

Read all the books from the first and second semesters of the second year of junior high school!

Ways to improve your academic performance:

1. Have a good attitude in class and be serious. If you want to concentrate on your studies, if you want to succeed in your studies, don't fall in love, don't have boyfriends and girlfriends, so that you don't have to worry about it, you don't fall in love when you study, you concentrate on studying, you will never regret it in the future, and there are many opportunities after you finish your studies.

2. It is inevitable to make mistakes in the learning process, whether you are careless or not, you must habitually collect these wrong questions, and establish a set of wrong questions for each subject, when we review before the exam, they are the key review objects, so since you miss once, you may not be wrong for the second time, only in this way will you not lose points again on the same issue.

3. The biggest difficulty for students is that they can't settle down, can't lift their energy, can't solve problems when they encounter them, can't figure out what to read, and can't jump out of the low tide all the time. Students, no matter what school you go to, you should have confidence in yourself, have confidence in your school, and work hard, no matter what the school's admission rate is, as long as you work hard, there is hope.

4. Next, we must adjust our physical strength, have sufficient physical strength, have good spirit, and be efficient in reading, sleep when it is time to sleep, don't stay up late, read well, and sleep well. In addition, extracurricular activities should be moderate, and they must not affect their studies, and it is not worth it to be busy with extracurricular activities and affect their studies. The activities that should be prepared, you should prepare well for the holidays, and if you want to participate in the activities, you can participate in the holidays.

Have faith in yourself and climb up no matter how good you have been. So if you work hard, you are giving people joy, hope, confidence, and working hard!

Cultivate interest, find the right method, take notes carefully in class, preview before class, and practice more after class.

Listen carefully in class, do more questions after class, be familiar with the question form, and ask the teacher more if you don't know.

Do the questions of the previous high school exams, master the methods from them, and extract the skills.

It is important to understand the whole process of each question, and it is especially important to understand the reasons for the mistakes.

Now that it's time to do the past questions wirelessly, the whole set of timing should be done, don't do the questions in a modular way, look at the answers after doing it, check the gaps, because the questions of the past years are the same

1. Adjust your mentality before class, you must not think, hey, it is another math class, and you will be in a bad mood when you listen to the lecture in class, so of course you can't learn well! 2. Be sure to listen carefully in class, and do it to your ears, eyes, and hands! This is very important, you must learn to take notes, if the teacher speaks fast in class, you must calm down and listen, don't memorize, and then organize it in your notebook after class!

Stay productive! 3. As the saying goes, interest is the best teacher, when others talk about the most annoying class, you have to tell yourself, I like math! 4. Ensure that every question encountered must be understood and understood, which is very important!

Don't ask, don't be embarrassed, learn to draw inferences! In other words, you need to be flexible! You don't need to do a lot of questions, but you need to be fine!

5. There should be a collection of wrong questions, write down the good questions and wrong questions that you usually encounter, and read more and think more, and you can't stumble in the same place!! In short, don't be afraid of difficulty, don't be afraid of tiredness, and don't be afraid to ask! You can ask this question here, which shows that you really want to learn math well!

I'm sure you'll succeed, come on!! The summary is the most important, including the summary of the classroom teacher, the summary of the self-preview review after class, the summary of the wrong questions, it is best to find a book, record the experience, usually turn over more, for the formula, the memory also needs to be understood, according to the specific situation appropriate use, pay attention to the scope of application of the formula. Don't equate physics with mathematics, especially calculate problems to develop a good habit of writing format.

For most questions, it is quite important to make diagrams, the key to the circuit diagram of electricity is to simplify, draw so that we can distinguish the connection situation at a glance, the force analysis of mechanics is the basis of the problem, the optical path diagram can help us analyze the problem, and even the boiling evaporation of heat will be used in the diagram Of course, it is easy to say, it will be difficult to do, but don't have pressure, I think the key to junior high school physics is to get started, touch the class will bypass more contact with reality, do more exercises, physics is very interesting.

Formula: Remember, figure out the relationship between quantity and quantity!! Then just apply the formula, and study to arrange a simple and feasible plan to improve the learning method. At the same time, it is also necessary to participate in school activities appropriately and develop in an all-round way.

In the process of learning, we must: listen more (listen to lectures), remember more (remember important question structures, concepts, and formulas), read more (read books), do more (do homework), ask more questions (ask if you don't understand), do more hands (do experiments), review more, and summarize more. Use the method of taking class notes to focus on the lesson.

In particular, it is easier to learn chemistry by memorizing concepts such as the periodic table, the priority of metal reactions, the conditions of chemical reactions, precipitation or gas conditions, etc. In other times, we must ensure the study time, ensure the learning quality of each subject, and not deviate from the subject. Get enough sleep (8 hours) every day to ensure your learning efficiency.

Arrange appropriate free time for socializing with family and friends and other activities. Through unremitting efforts, the results are improved and stabilized step by step. Do your best for the exam, be careful during the exam, and be calm when you sprint at the end.

After the exam, you should summarize carefully so that you can study better in the future. Right now: let go of the baggage, usually:

Study hard. Before the exam: Prepare carefully, during the exam:

Don't give up, after the exam: normal heart. Remember!

Learning mathematics, physics and chemistry is not only to learn book knowledge, but also to understand the content explained by the teacher, and to take the small experiments in the classroom seriously, because although the experiments are small, they cover a large area, and this list of experiments will also be helpful for the understanding of the theory; In addition, some interesting experiments can also stimulate one's research interest. In this way, the textbook knowledge can be learned well.

Then in daily life, we should pay attention to observation, and many places in life will be related to mathematics, physics and chemistry. Ask a few more whys, and then try to explain what you have learned, once you solve a problem yourself (e.g. why did you start the teapot lid is lifted up, why does the river flow down...). There will be a sense of accomplishment, which will boost self-confidence.

Learning is also more motivating.

Hope it helps.

Listen carefully in class, do more exercises on weekdays, write down what you don't know, and review it again before the exam. It's best to have an error correction book, write down the questions you don't know on it, and look at it if you're okay, so that you can definitely do well in the exam. I wish you progress!!

It is necessary to understand every knowledge point as thoroughly as possible, and then do a large number of questions in a targeted manner, record all the questions that are wrong, and do it repeatedly, as long as you understand it!

It is not enough to practice more and just read the textbook.
