First, and most importantly, you have the belief to learn it well. The landlord should already have it.
Second, textbooks. Textbooks are all basic things, and you can skip the questions before the exam and not read the wrong questions, but the books must be read. When reading books, pay attention to details, equations, reaction phenomena, and special physical or chemical properties of a substance must be paid attention to and memorized carefully.
Third, attend classes. The teacher must listen carefully to the lecture. If you can't keep up, do a good job of preparing.
Fourth, exercises. The landlord's grades are not good, so I recommend you to start with easy. Get a paper and do it well first, do it well, catch it, and then go to overcome the problem. You don't have to be more, you need to be refined.
Fifth, summary. For example, the method of chemical calculation problems (difference, conservation, etc.). Then there is the wrong question. Of course, not all the wrong questions, as long as the classics.
Sixth, communication. Communicate with your classmates, communicate with your teachers, especially teachers, who have the experience to show you the way. Since the teacher has paid the money, it is necessary to seize the opportunity to ask more questions and communicate more.

There are two large blocks: inorganic and organic. It is enough to memorize the main group part of the periodic table inorganically, and the properties of the elements of each group are all in the book, which is very detailed. Organic matter, graded laws, all laws are talked about in books.
Learn inorganic a week and learn organic a week, and immediately take the exam with more than 80 powders.
-
Memorize the key chemical formulas, which are often tested in exams, and in addition, there is a special method, which will not be used to check the textbook at any time when doing the questions and remember, this method is suitable for various subjects. Dear, if the method is good, remember to give points.

In fact, I think interest is very important, when learning chemistry, you can connect it with life, really like chemistry from the heart, listen carefully in class, improve class efficiency, and complete homework on time.
-
Memorize the equations (organic, inorganic, electrochemical) and you memorize them.

Chemistry is actually not scary or annoying, and it will be easy to learn if you have a good impression of it. To clarify the reaction law of acid-base salts, the concept of the periodic law chapter must be understood. Be imaginative in the experimental part.
Don't panic in the calculation questions, the coefficients of the equation must be correct. To do a question, you must not only know what it is, but also know why it is so. Xiaopeng Sina blog has a good summary of chemistry learning, and there are study guides and learning blog posts for various subjects in the blog, which are all summaries of the blogger's learning experience, you can also take a look!
I thought his unique learning blog post would help you. Everyone says that chemistry is a liberal arts subject in science, and you have to memorize it. And junior high school is inorganic.,It's more scattered.,It's best to sort out a reaction vein.,If you don't have time, you can buy a tutorial book to read it.,But you must have your brain and remember it.。

It depends on whether you are in high school or junior high school, and chemistry is still different at different stages.
In junior high school, just memorize the chemical equations in the book, and then memorize the process and results of those big experiments, and practice two questions.
If you are in high school, you must do more questions, you must listen to them in class, and you must memorize all the equations of the day, otherwise you will not understand them in the next class. If you are studying science, you should pay attention to learning mathematics well, which will help you with chemistry. High school chemistry is more difficult, but not as difficult as physics, so you should also allocate your time wisely.
Don't be superstitious about the tactics of the sea of questions. Pay attention to the parent body (example questions) must be remembered, especially the example questions of some common test centers.
Hope it helps.

Listen carefully in class.
Assignments are completed on time.
Practice more after class.

Learn the way you like and don't just imitate it.
The reasons for poor chemistry grades are that they like to delve into difficult and strange questions, do not pay attention to the systematization of knowledge, and are not good at summarizing and inducting. >>>More
The basic solution to the difficulty in class is to ask positive questions, and you try to raise your hand for every question the teacher asks. Although you may have poor grades and answer all the wrong questions, the questions will increase your motivation, don't be afraid of your classmates laughing at you, they are not as good as you. At the same time, the teacher will see that you want to improve your grades, and he will take more care of you. >>>More
Primary school students' grades are poor, parents can tutor, you just be patient, don't lose your temper, help your child out of the predicament, usually give your child more Chinese books, more literacy, good Chinese scores, will drive math scores will also rise.
1. Listen carefully and take good notes. Good notes are the condensation, supplementation and deepening of textbook knowledge, and the presentation and refinement of the thinking process. Since the knowledge points of chemistry are numerous, fragmented and scattered, in addition to listening carefully and thinking positively, in addition to listening carefully and thinking positively, we should also write down the key and difficult knowledge of the teacher in our own words on the basis of understanding, so as to facilitate future review. >>>More
Science, you can exist is science, after all, mathematics is different from physics, physics is relatively figurative, mathematics is more abstract, the two disciplines are not exactly the same, in fact, people who are good at physics may be creative, because they are good at imagining.
