High school chemistry can be divided into three major sections for review: inorganic chemistry, organic chemistry, and principles of chemistry. Inorganic chemistry should use the periodic law to dominate the overall situation and memorize the properties of typical elements. Organic chemistry, understanding the reaction and evolution of functional groups; To understand the principles of chemistry, this is a bit difficult, you can find a tutor to tutor it.
-
Hehe, textbooks, do some test papers, familiarize yourself with some.
-
To learn chemistry, first of all, you should follow the textbook and don't read too much information, which is useless, the textbook is the most authoritative. And you can master the basics carefully, and only then can you get the 42 points of your choice, right? You need to memorize more equations to solve problems, and memorizing the physical properties of matter can also score points in the experiment.

1.The system has passed the book, the old textbook is better, and the new textbook is too frustrating Chemistry belongs to the liberal arts in science, first memorize by rote, and complete the after-class exercises, 2Find a review material that teaches shallowly, do it seriously, and the person who writes the question must test a knowledge point for each question, and review the knowledge points through the question.
3.Teacher Dead Catalpa doesn't let go, just ask if you don't understand.
-
It is recommended to find a tutor to make up for it!It seems a little late to come by yourself!
-
Read more textbooks, memorize knowledge points, grasp the basics, and do some practice problems.
-
Summarize the formulas together, memorize them, and then read more textbooks, it is best to borrow other people's knowledge points to find them, and just watch them. Chemistry is all about seeing more and remembering more.
-
In science, chemistry is a subject that can be improved quickly in the short term, so you must have confidence first
There are a lot of knowledge points that need to be memorized in chemistry, so it is very important to work hard to memorize them.
Before the teacher's review, you should preview in advance, and when reviewing each section, find out the relevant chapters of the textbook, look at it carefully, write down the equations, the properties and concepts of the chemical elements involved, etc., and summarize the main knowledge (there is a knowledge point to fill in the blanks before each section of the general review book, which should be paid attention to), and ask the teacher and classmates if you don't understand the place, and the concept must be understood.
Then you can look at the example questions, look at the solution ideas and methods of the example problems, and you can also think about it by yourself before reading, and after reading an example problem, you can find the same type of question in the later practice questions and try to do it yourself.
Just repeat it and keep doing it; This is the idea of a round of review, if you can pass this level steadily, you will be able to play it with ease later, just follow the steps of the teacher.
You may be a little discouraged at first, but you can't despair, I have a classmate like you, but if you persist like this, the college entrance examination is still very good. Therefore, we must be serious and steadfast, and we will definitely succeed if we stick to the end.

1. In the review of the college entrance examination, we must learn to sort out our own learning situation, based on textbooks, combined with the notes and test papers we have made, the weak links we have mastered, and the existing problems, etc., allocate time reasonably, and tackle and implement them little by little in a targeted and specific way. If you don't grasp the content well, spend more time, and when you review, you should be systematic, don't go east and west, and end up reviewing nothing.
2. You can learn to master the ability of speed reading and memorization, and improve the efficiency of learning and review. Speed reading and memorization is an efficient method of reading and learning and revising with direct reflection of the eyes and brain. For the practice of speed reading memory, see "Elite Special Whole Brain Speed Reading Memory Training", practice with software, more than an hour a day, a month's time, you can double the reading speed, memory, comprehension, etc., and finally improve the efficiency of learning and review, and achieve good results.
If your reading and learning efficiency is low, you can practice it well.
3. Learn to integrate knowledge points. Classify the information you need to learn and the knowledge you need to master, and make it into a mind map or knowledge point card, which will make your brain and thinking clear and easy to remember, review, and master. At the same time, learn to connect new knowledge with what you have already learned, and constantly integrate and improve your knowledge system.
This promotes understanding and strengthens memory.
4. When doing problems, you should learn to reflect, classify, and sort out the corresponding solution ideas. When you encounter the wrong questions (carelessly do it wrong, you can't do it), it is best to collect these wrong questions, and each subject has an independent set of mistakes (the set of mistakes should be classified), and when we review before the exam, they are the key review objects to ensure that there are no more mistakes and points on the same questions.

1. First of all, it is clear that any chemical reaction should be considered from the perspective of the periodic table.
The reaction principle of chemistry is the question of whether the outermost electron shell is "saturated", and the valency of the state of matter is basically in line with the law of the periodic table, and only a few polyvalency are to be copied and remembered. Make a notebook specializing in chemistry and keep a "non-conventional" record, including all reactions of special colors, gases, precipitations, valences, etc.
2. Secondly, the key records and special elements must be kept in mind to distinguish them.
Special elements are elements that can produce special gases, precipitations, and colors by reaction, as well as valence elements, combination elements (acid roots), etc., which are the test points and starting points for solving problems in chemistry in the college entrance examination. In this blog, there is a complete set of starting points for inductive chemistry problem solving, which is full of special reactions and easy-to-mix knowledge points. I hope that everyone will summarize it for themselves, and not think that with this content, you can sit back and relax.
3. Use comparison and seek differences from the same.
There are similarities, differences and interconnections between some elemental compounds in elemental compounds, which are easy to cause confusion, for these substances, the comparative method can be used to conduct comprehensive analysis, and one by one to carry out comparative analysis to find out their commonalities and differences, so as to obtain solid, systematic and accurate knowledge.
4. Connect with reality and use flexibly.
In the review, the element compounds should be closely linked with practical problems such as production, life, environment, nature, and energy as much as possible, so that students can feel that chemical knowledge is the source of water and the wood of the root, and that learning chemical knowledge is not only for examinations, but also has practical significance.
1.Consider setting some time limits for yourself. It is easy to get bored by studying for a long time, so you can divide the homework into several parts, and set a time limit for each part, such as completing the exercise within an hour, completing the test before 8 o'clock, etc., which will not only help improve efficiency, but also do not cause fatigue. >>>More
How to say that?
1 mole of any particle or substance, when its mass is measured in grams, is numerically related to the phase of that particle. >>>More
It is recommended that you buy some more comprehensive reference books that summarize, some books can be classified and summarized all the chemical reaction equations under this category, you only need to memorize the typical ones, summarize which parts of yourself are weaker according to the usual exams, do not buy units according to textbooks, buy those that are classified separately, it is better to say organic chemistry, inorganic chemistry and the like, if you memorize better, buy written knowledge with more questions and fewer topics, and if you think it is more helpful to do the questions, buy more topics This is my previous learning experience, I don't know if it will help you
I've been through my senior year of high school, and it's not been long since I'm in my first year of college. >>>More
The habit of doing questions is not good, he must not have read the 4 options, as soon as he saw the answer he thought was right, he immediately chosen, so it is easy to make mistakes, after all, the examination may be wrong, see the missing words, read too many words, knowledge loopholes, etc., may lead to mistakes. >>>More
