How do I learn mathematics, physics, and chemistry well? What s the method?

There is not much connection between junior high school and high school, so I think you should start from high school, mathematics and physics I think it's about the same, first read books (including reference books), see the definition, some information books are still very good, and then there are example problems, I am now in my third year of high school, physics is generally about 90 points, not low, the main thing is that it is very important to think by yourself, see a question first to clarify the idea, to dare to write, physical schematic diagram (mechanics, or kinematics) is very important, and then the different categories of questions will do some. Mathematics and physics are almost the same, the main thing is that you dare to write, don't look at it and don't do it. Some questions are calculated, and there is a feeling of "the mountains and rivers are full of doubts, and the willows and flowers are bright and another village".

As for chemistry, I am not very good at chemistry, the teacher said, to be good at classification, chemistry is very scattered, each piece is not too difficult to learn, but even up there is no idea, so to be good at classification, summary, reflection, like sorting out "common oxidants and reducing agents", "common acid oxides", "different collection methods of different gases". There is also chemistry to find special, just like "ammonia is the only alkaline gas", "aluminum oxide is the only amphoteric oxide" exam to test special, I think what the teacher said is very reasonable, it is not bad to use, I will tell you.

That's all, personal hand-hitting, I hope to be satisfied, thank you, I wish you progress.

You can follow up.

If you understand the principle, chemistry is actually not difficult, and many equations are derived from basic formulas. Memorize a few basic equations first, and the rest is much easier to memorize. I don't know what chemistry you study.

The theoretical requirements of junior high school chemistry are only more, and they are generally inseparable from equations, and mastering the equations can almost guarantee a passing grade (past experience, I don't know if it is still applicable now, because it seems that a lot of practical things have been added to the curriculum) At that time, the teacher always asked us to do some ** or summarize some things, starting from the basic reaction equations, and then expanding the reactions of some specific substances, such as special precipitation or gases. It's easier to remember from easy to hard. There is a lot of common sense knowledge in chemistry, and it is easy to remember when combined with life, I basically rely on these to score, and the accuracy rate of calculation questions is not very high, but the proportion of calculation questions is small.

In fact, junior high school mathematics is not so difficult, it is guaranteed that you will learn it as soon as you learn it, and really as long as you master the knowledge points and formulas, it will not be difficult to solve the problem at all.

You don't have to memorize by rote, it's not okay to pull out the seedlings and help them grow.

Don't put pressure on yourself, or you won't be able to perform well in the exam.

In a word: just memorize the formula.

Do more questions, do the questions to summarize in time, summarize the question type, mathematics, physics and chemistry also rely on memorization and recitation, memorization and recitation of the question type, one question type corresponds to a method, so that you will learn well.

Grades are divided into examination ability and study ability.

I don't know what kind of person you are.

I often got full marks in junior high school physics exams, and there is no secret, just curiosity, cultivating an interest in physics, making myself curious about physical phenomena, and wanting to specialize in what is going on, so I naturally did well in the exam.

Mathematics, Physics, and Chemistry are all science subjects, and their learning methods can be shared! First: Be confident.

Many scientific studies have proved that human potential is great, but most people do not effectively develop this potential, among which human self-confidence is a very important aspect. Whatever you do, whenever and wherever you do, with this self-confidence, you have a belief that you will win, and it will enable you to quickly get rid of the shadow of failure. On the contrary, if a person loses his self-confidence, then he will achieve nothing and can easily fall into eternal inferiority.

Second: With scientific learning methods, you can achieve twice the result with half the effort in learning. In terms of improving efficiency:

There are learning links, learning attitudes, and learning methods. As long as you change your studies from now on, and you study hard, of course, it will be simple, and your grades will improve. Everyone's foundation is different, and their learning attitude is different, so the methods to be adopted are also different.

In order to learn well, you must find a learning method that suits you, and you must choose a suitable method according to your own characteristics. You can make progress. The method of learning should be "a hundred schools of thought contending" and "a hundred flowers blooming".

Third: the key to the exam is your mastery of the subject. Basic disciplines account for 60, mid-range questions mainly test skill application accounts for 25%, and high-end questions account for 15%, which are mainly the examination of comprehensive ability and application ability, mainly to distinguish high-level students.

Exams, don't be too nervous. As long as you look at the score, otherwise you will be too nervous and you will not be able to review. Everyone is nervous about the exam, but don't be afraid, don't be nervous.

1.A comprehensive review of the basics. 2.

Analyze the existing problems in detail, and do a good job of reviewing the gaps 3Review in sections. Do the same in the differences, the same in the differences.

4.Thematic review. Cultivate comprehensive ability and expand your application ability.

Why do you need to meditate?

Just ask a few more whys.

If you want to learn mathematics, physics and chemistry quickly and in a short time, you can only do some representative examples.

There are teachers who teach both knowledge and good learning methods, and the so-called famous teachers produce high apprentices, which is the truth.

Do a lot of practice questions for the corresponding range.

The fast learning method of chemistry (if you understand the basic knowledge) memorize more chemical equations and summary equations, and the senior year is how to improve the feeling The effect is very good, and I am not afraid of unfamiliar equations during the exam and I know it in my own mind, and I do the questions quickly. Physics and mathematics are both chronic, if you improve quickly, first grasp the basic concepts, discard some difficult problems (for senior and senior high school students), get 80-90% of the intermediate problems right, and then brush up a lot.

Personally, I think it is necessary to start with typical problems and gradually excavate, so that you can take the initiative to learn and make rapid progress!

Hello, I have 3 suggestions that I hope can help you:

Interest: If you like it, you will be motivated to learn, and you will have fun.

Do more questions: Exercise thinking, discover methods and improve logical skills.

Communication: Communicate with teachers and classmates around you to see how they do it, and find out how to learn that suits you.
