    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!

First of all, the foundation must be firm!! To what extent it depends on how many points the landlord wants to score. The second is to do more questions, the purpose is to practice how to comprehensively use the basic knowledge (not the sea of questions, but to understand one question and understand one question). >>>More

I really want to tell you the truth, the basic knowledge of these three subjects is actually not difficult, but now after the new curriculum reform, as long as students learn the content that needs to be explained in the textbook, there will be no difficulties. But we should not deny the fact that for large-scale exams, it refers specifically to the college entrance examination, and the content of the test will definitely not be as simple as the content of the textbook, but a large number of complex and comprehensive application of textbook knowledge. To put it in layman's terms, the textbook knowledge is straightforward, but the content of the exam has to give you a few turns, and some of the questions are even more suspicious, set traps but there are some simple shortcuts, which reminds me of the comprehensive use of the ancient Art of War in modern exams. >>>More

Don't worry, I'm also a freshman in high school, I don't know how you did in the entrance exam, anyway, I didn't get into a good class, it's all bad living habits and methods, classmate, I was in the same hurry as you in the first semester of my freshman year of high school, and I really wanted to do well in the exam so that I could get into a good class, but it backfired Not only did I not study well, but I also studied very tired, and I started to adjust when I was in high school, and now the more I learn, the more motivated I became, and the teacher told us that I didn't let you study well in the first year of high school, and it doesn't matter if the science in the first year of high school is not very good, the important thing is to get a high score It's a bit contradictory, but it's not a contradiction The first year of high school is the beginning of high school, is the time to find a suitable learning method for yourself, so the knowledge is relatively not too difficult, the questions are not difficult, it is easy to learn well, as long as there is a good method, well, enter the main topic, mathematics is not difficult to learn, it depends on whether you are interested in the method or not, and it is a little late to cultivate now, but the math score is very good, you first read the book, read the questions, write the questions in the book, and then do the example problems that the teacher said, and finally write a little information, and the speed and accuracy of practice must be sure to lay a solid foundation or it will be a tragedy The same is true of chemistry The difference is that the catechism knowledge points Chemistry is very messy If you ignore it, it's quite slow to do the questions, and it's still wrong, and you can try to think of the knowledge framework in your heart, think of some example questions, methods, and things to pay attention to in the knowledge points, which you had better leave until you understand the textbook thoroughly and do it, otherwise it's a fantasy, not to know if you understand, to say that the simple point is to read the book first, understand, and then write the questions on the book, the classic example questions must be able to write a little information on the questions, and finally think about the knowledge framework, think of each knowledge point, think of the place you want to pay attention to, think of the example questions, think of the method, the foundation must be solid, otherwise the score is up and down, quite terrible The second year of high school liberal arts and science key class You have to work hard Don't relax and work hard for a month or two is definitely enough to improve the right to improve the science method first, diligence secondly, not to make you lazy It is to emphasize that there is a method that suits you, and a little effort is a high score Not only is it very motivating, but also not too tired You must summarize the method by yourself My method is not the best You must improve it appropriately in combination with your own situation There is also a daily exercise will relieve the pressure of studying, which is very useful I wish you success in your studies I am admitted to a good science class Ten years of hard study Once the title of the gold list is titled, there will be problems in the future, I hope we can be together**.
