I chose materialization, only to find out that it was so difficult! How do you learn it?

For children in Jiangsu, materialization should be the most difficult combination of several elective courses, and relatively speaking, the competition is also the strongest. You should first be proficient in the basic knowledge context of these two courses, and it is important to lay a good foundation. In class, you must listen carefully to the teacher, these dozens of minutes are very important, and it is much more to gain in the classroom than to blindly remedy it on a large scale after class.

For physics, whether it is mechanics, optics or electricity, the force analysis diagram is very important, it can help you better understand, if there is a lack of drawing, you should ask the teacher for advice in time, and there will be special training drawing materials in the bookstore, summarizing, I think it is very practical. For chemistry, high school chemistry is naturally not comparable with junior high school, the conditions are good, it is best to do experiments yourself, so that the impression is more impressive, on the basis of familiarity with the law of reaction, proficient in chemical equations, in addition to the periodic table is also very important, it will be linked to the organic chemistry you want to learn next, the periodic law can help you solve a lot of problems, when you learn the book of organic chemistry, the spatial structure must be clear, if you don't understand it, go to the teacher to ask, the teacher must have a geometric model, to help you understand. As for correcting mistakes, the teacher must have emphasized that it is necessary to reflect after school, and it is not easy to ensure that the wrong questions are not wrong again in the high school stage with heavy tasks.

The practice after class should also be strengthened, to choose a suitable material for yourself, practice a few times a day, not greedy, the key is to summarize and reflect, and integration is the highest level. Usually, you can also flip through the information of your classmates, and everyone can discuss and discuss together, and complement each other's shortcomings. If I'm not mistaken, the landlord has just entered the second year of high school, so I want to remind you that compulsory subjects are also very important, after all, the small college entrance examination plus five points will have an extra insurance, maybe it can also make the college entrance examination score go up a notch.

As for the elective subjects, don't worry too much, after the end of the small college entrance examination, the progress of the elective subjects will soon end, and then it will enter the stage of comprehensive review.

Physics focuses on the set of formulas and then to understand, chemistry is mainly to memorize the basic knowledge, and the basic knowledge can be mastered by proficiency.

Nowadays, many students want to know how to learn junior high school chemistry well, and they don't know where to start when they learn this course, this problem is very difficult for them, now let's find out how to learn junior high school chemistry well!

Chemistry is a basic discipline that studies the composition, combination, and change of some special substances, and it has a very great role in agriculture, society, science, etc.

How to learn chemistry well in junior high school?

1. Understanding. When learning these courses, you need to understand the concepts and theories, which are necessary knowledge points for learning all courses, and you also need to have a very good foundation, generally these concepts are expressed in very simple sentences, so you need to grasp the key, and then memorize.

For example, catalysts, a concept that generally requires comprehensible memorization such as sum, equality, and so on. These concepts not only need to be correctly understood, but also need to be used correctly, and generally speaking, chemical professional terms refer to some sentences expressed in the experiment, such as element symbols, etc., which are all content to be fully mastered and used correctly.

2. Structure. In this course, it is necessary to know the structure of the object under study, which is directly related to the nature of the object under study, and the nature will affect the state of existence and use of these substances, so it is necessary to grasp the structure of these substances to make judgments.

For example, oxygen, you need to think about what it is made of and what space it can exist in, what kind of substances will cause abnormal reactions, and under what circumstances it will cause harm to the body, etc.

3. Test. In the study, the test accounts for a large proportion, the students need to carry out their own work, need to know how to separate, purify, identify, etc., in the analysis of the need to draw certain conclusions through some specific means, in the use of the instrument needs to be careful, in the process of doing as correct as possible, the results should be more obvious, in the teacher demonstration needs to be patient observation, a comprehensive understanding of its principle, so that they can carry out the test without error.

4. Learn the law. When studying, you need to find your own learning style, there are many contents in these courses, so if you don't study properly, your score may drop, and it is very important to find your own learning style.

The above is about how to learn chemistry in junior high school, I hope the above content can help you when students learn chemistry.

If you are now in the third year of junior high school, you can't start from the very basics, you can only brush the questions, but after brushing the questions, you must make a summary of the wrong questions, rearrange the questions, write the process and analysis doubts clearly in a notebook, and do it again and again, until you see these questions, you will find that this is actually the same as the test point of this test, this method is also used by myself, I am already a sophomore in high school, and the method has been used for several years, and the effect is really good.

Physics: Prerequisite: Learn mathematics first. Because mathematics is the foundation and tool of physics.

First, memorize the definitions, laws, theorems, and laws in physics.

Second, clarify the relationship between physics knowledge.

Third: do more questions, practice makes perfect.

Fourth: Do comprehensive questions.

Fifth, experiments are a very important part of learning physics, which can deepen our understanding of physics knowledge and cultivate our ability.

Chemistry: Prerequisite: Learn math first. Because mathematics is the foundation and tool of chemistry.

First, memorize the definitions, laws, theorems, and laws in chemistry.

Second, clarify the relationship between chemical knowledge.

Third: do more questions, practice makes perfect.

Fourth: Do comprehensive questions.

Fifth, experiments are a very important part of learning physics, which can deepen our understanding of chemistry knowledge and cultivate our ability.

Since I chose objectification back then, I'm inclined to you to choose objectification as well (maybe a little biased).

First, whether it is a liberal arts student or a science student, they must learn more than mathematics. Here, you have to be clear:

Liberal Arts Students: Chinese: 1 paper: 160 points + 2 papers (additional questions) 40 points = 200 points.

Mathematics: 1 paper: 160 points.

English: 120 points.

Science students: Chinese: 1 paper: 160 points.

Mathematics: 1 paper: 160 points + 2 papers (additional questions) 40 points = 200 points.

English: 120 points.

Analysis] Whether it is a liberal arts student or a science student, Chinese (one paper), mathematics (one paper), and English are the same. The only difference is that liberal arts students take the Chinese additional questions, and science students take the mathematics additional questions.

For the supplementary part, the things that are studied in the liberal arts are basically not helpful for doing the questions in the first volume, while the things that the science students learn are very helpful for the questions in the first paper.

To give a few examples: space vectors --- helpful for solving solid geometry.

Derivative of the composite function --- 1It is helpful for solving function problems (liberal arts students will not find derivatives for compound functions, and when they encounter a problem, if they can't find an ingenious solution, science students have the "last **" - derivative, and liberal arts students obviously suffer a lot); 2.When solving the last big problem, it will be much easier to learn the derivative of composite functions.

Parametric equations --- helpful for solving analytic geometry.

Moreover, it is easy to get points for additional questions in science, and it is difficult to get points for additional questions in liberal arts.

Second, for the small college entrance examination, the points that can be added are insignificant, and it may be a matter of a math fill-in-the-blank question (5 points), so you don't have to be too nervous.

Third, you also said that finding a job is easy for science students to find, so I won't talk about it anymore.

Fourth, in fact, everyone is similar, the vast majority of students rely on the training of a large amount of questions to achieve results, and the scores are originally obtained by listening well to the lectures and doing more questions.

Fifth, don't worry about the elective books of physics, it is not as difficult as you imagined.

Elective 3-1, Elective 3-2: These two books should be studied hard, and the answers to the questions are basically selected from these two books (but as long as you do more questions, there is nothing difficult.) Suffice it to say, these two books are definitely no more difficult than Newton's second law. ）

Elective 3-4, Elective 3-5: When it comes to the college entrance examination, these two books only test the most basic, as long as you memorize them, there is no difficulty.

However, the elective in chemistry is more difficult, especially the book "Principles of Chemical Reactions", so be prepared!

Sixth, if everyone really reported physical chemistry, you should laugh. You must know that physical chemistry is graded according to proportion, and the more people who apply, the more cardinal it is, and the higher the chance that you will get a grade above B.

That's all for my analysis, I hope it will be helpful to you.

You're only in your first year of high school, and you've learned very little. Don't judge which course you are suitable for because of the results of several exams, I am also from Jiangsu, a science candidate in the class of 09.

If you choose science, you must be good at physics, physics mainly depends on your comprehension ability, and chemical memory has more content. Also, don't think that it's okay to memorize liberal arts, some topics are still difficult. If you think that you can gain a foothold in the liberal arts class because of a certain grade in history, it is too superficial, history is an elective course, it is very important, but others will endorse it, and the gap may not be big at that time.

Liberal arts students also have a lot of math skills, and you don't seem to have much of a sense of language.

As for the additional questions, you don't have to think about it, because the admission of arts and sciences is originally separated, and there are a total of four additional questions in mathematics, the first four choose two, and the last two must be done, and most of them are still simple.

There are a wide range of science majors, so if you are confident in mathematics and physics, you should choose materialization.

If you choose materialization, you should remind you that there must be more questions to do in science, so that practice makes perfect. Physics must understand the situation before writing, and must not blindly apply formulas, and chemistry should still be memorized.

Good luck.

I'm a sophomore science student....Personally....I prefer liberal arts, but in the end I chose science, the learning pressure of science is very high, but the pressure of going to school is only about one-third of that of liberal arts, and most of the liberal arts students have learned specialties (that is helpful for further study), I personally feel that the learning pressure of science is very high, especially physics, which is more difficult, chemistry is fine, and history and politics should be relatively simple for those who are interested in this, our situation in Hunan may be different from yours, but science students are still better when looking for a job, Because if you choose a major in college, science students can choose liberal arts majors, but it is difficult to learn science majors well in liberal arts, these are my own thoughts, you still have to consider this kind of major event, and you will never regret the choice of being loyal to your heart....

These subjects are basically memorized tests, so after each lesson, you must consolidate the familiar reading and memorization in time. In addition, according to my experience, in addition to memorization, it is very important to master the classroom when studying politics. Although most of the multiple-choice questions in politics are written points that are required to be memorized in textbooks, there are also analytical questions, material analysis and explanation questions, and sometimes practical questions to formulate activity plans.

This kind of topic requires the ability to understand it on a daily basis, but of course it can be cultivated slowly. It is also necessary to master problem-solving skills, such as what the material says about what it tells you, and analyze it from both positive and negative sides. Analytical questions are usually judged first, then analyzed, and the analysis process should be centered"What, why, how"Write and finally point out your point again.

In fact, if you want to learn anything, you should be interested in it first, (this is the premise) only if you are interested in them will learn it. And then exchange hard work for fruit (this is the key) There is no free lunch in the world, even if a person with great talent does not study hard, the final result will be no different from ordinary people, and even catch up with ordinary people. If these two things are done well, there is nothing to fear.

When I was in my first year of junior high school, these three subjects also gave me a headache, but I finally beat them. That's how I beat them.

I always think, can't I do what others can do? It turns out I could.

You have to believe in yourself, too!

In fact, I had similar confusion in the past. But now there are a few good ways! But multi-pronged!

First of all, doing the question is a must! But to know what it is, but also to know why! Otherwise, you're just wasting your time!

Secondly, pay attention to the lectures! This is an inevitable requirement for learning any subject well! Third, you should always ask the teacher, the teacher can accurately grasp the main points of the question, and asking the teacher a question is better than pondering 10 questions by yourself!

Fourth, pay attention to the usual accumulation, and don't just focus on the textbook! The high school geography exam is not only a textbook knowledge, it is very comprehensive, and you can watch more programs about geography on TV at ordinary times, which is the process of accumulation, and you can also look at more maps! That's all a great way to do it!

Follow these methods and I'm sure you'll reap the rewards! That's how I progressed! I'm sure you can!
