How can you quickly improve physics and chemistry

The memory should be strong, the understanding should be profound, and the application should be flexible! Can.

Equations, properties, and rules are just a matter of memorization.

1.Attention to detail. Many people only hold this workbook and do it, but the results do not improve. Books should be read carefully. Read the notes under the book, the large and small print parts, **, after-class exercises, etc.

2.Focus on the basics. A lot of people focus only on the hard questions.

Of course, there are difficult problems to do, but you must know that no one can afford to lose 6 points in the college entrance examination, and the multiple-choice questions are relatively basic, which shows the importance of the foundation. Then whether you are clear about the physical quantity units, quantitativeness, formulas, and conditions for the use of formulas? The physical and chemical properties of substances in chemistry, the writing of reaction equations, and the reaction conditions are clear to you.

3.Focus on synthesis. Comprehensive questions are the superposition of many knowledge points, which requires you to clear the loopholes of each knowledge point, pay attention to the analysis of physical processes, be careful and meticulous, consider comprehensively, and calculate carefully.

Finally, I wish you excellent results in physics and chemistry.

The basics of physics are important, and they need to be careful.

1. Physics: 1It's all about analysis.

Be sure to do a good job of analysis before solving the problem.

Physical force.

Known conditions, problems sought, interference conditions, and so on.

2.Mastery of formulas.

Mastering formulas is the only way to solve problems in physics, including mathematics.

Of course, if you might not understand how a formula is derived, that's okay.

It doesn't prevent you from solving the problem, but, you have to memorize the formula.

For example, the question requires speed v

You immediately have in mind the formula for linear motion with uniform speed.

1) Speed formula: vt=v0+at

2) Average velocity formula: v=(v0+vt) 2(3) Displacement formula: s=v0t

1/2at^2

4) Velocity-displacement formula: vt 2

v0^2=2as

VT not included: s=v0t

1/2at^2

does not contain a:s=(v0+vt)*t 2

Does not include s:vt=v0

At and so on, add your analysis of the known conditions of the problem, and soon you will choose the best formula to solve the problem.

So, please memorize as many formulas as possible, if you don't understand, it's okay, just memorize it as a 99 multiplication table.

3.Summary. Please summarize the knowledge points.

Please summarize your mistakes after each test.

You will find fewer and fewer problems stumping you.

You will find that it turns out that the test comes and goes.

2. Chemistry. Some people say that chemistry is the liberal arts of science.

That's true. Chemistry requires a lot of you to memorize, the types of elements.

The state at room temperature, color.

Lots of reactives, and so on.

So for chemistry, please keep in mind.

Fortunately, the junior high school chemistry test is basically a very common element and compound, so it should be okay to memorize dozens of common elements and compounds.

Listening is the key, thinking is the core, whether you can be highly concentrated in the classroom, concentrate on listening, and eliminate all distractions and distractions to concentrate on listening is the key to determine the efficiency of learning. Some students are not concentrating in class, taking a nap, making small movements, and not paying attention to listening to lectures, and making up classes in their spare time, it is like picking sesame seeds and losing watermelons. More importantly, you should also be able to listen to lectures, not only listen to the ins and outs of knowledge, but also be able to understand concepts and example problems, and at the same time learn and feel the methods and ideas of each knowledge point taught by the teacher.

In order to learn how to take notes skillfully and completely, you must develop the habit of listening first and then taking notes in class, think about and organize what you hear, and outline the key points and difficulties of this section, the content that must be mastered and the content that is not in the textbook, easy to make mistakes, easy to confuse or inspiring to yourself. If you don't understand what you didn't understand at the time, you should consult your teachers and classmates in time after class. It is also necessary to remember the content of the textbook, divergent questions, and the consolidation, testing, and improvement training questions that are required to be completed in class.

After class, you should organize your notes comprehensively and systematically, and record your understanding and feelings of what you have learned. This process can improve each student's understanding, that is, the process of digesting and understanding into their own knowledge.

The basic essentials of chemistry: proficient memory + practical operation, that is, chemistry is an experiment-based discipline, and learning should combine proficient memory with practical operation.

Learning should be arranged with a simple and feasible plan to improve the learning method.

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.

That is, it is necessary to memorize the position of the first 18 elements in the periodic table, the characteristics of atomic structure, and the relative atomic weight and relative molecular weight of common substances, so as to improve the speed of problem solving.

The chemical properties of chemicals should be understood and mastered, especially familiar with the writing of chemical equations and ion equations. It is necessary to have a comprehensive grasp of the use of chemical laboratory instruments, the basic operation of chemical experiments, and be able to design some typical experiments.

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!

The way to improve your chemistry score is to find the wrong questions, find the wrong questions and figure it out, then find similar questions, and do similar questions after a week.

If you want to improve, you have to carry it, and if you carry all the food you eat, you will improve.

If you want to improve quickly, you need to find a tutor who can make up for it.

If you want to improve quickly, then you have to do more questions, do more rules, and you will be familiar with the routines.

Chemistry is actually relatively simple, as long as you master some basic chemical principles, many things can be inferred.

How many questions do you want, then listen carefully in class, take good notes, and review after class. Listen to the teacher.

The summary is the most important, including copying the teacher's summary, the summary of self-preview review after class, and the summary of the wrong questions.

Don't equate physics with mathematics, especially calculate problems to develop a good habit of writing format.

For most problems, the diagram is quite important, the key to the electrical circuit diagram is to simplify, 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 use the diagram.

Of course, it's easier said than done, but don't be pressured, I think the key to middle and high school physics is to get started, and touch will be bypassed.

Physics is very interesting.

Chemistry: The basis of chemistry is nothing more than elements and chemical reactions, and the main chemical reactions in middle and high school are nothing more than redox reactions, I think you should first have a good grasp of the principle of chemical reactions and know what chemical reactions are all about.

The steps are as follows:

1. Have a deep understanding of what a chemical reaction is and what are the main components of a chemical reaction.

2. To learn redox reaction, you must know what is oxidation reaction and what is reduction reaction.

3. Memorize and memorize commonly used chemical reaction equations and typical chemical reaction equations.

4. Read the texts carefully to enhance your interest in chemistry.

5. Enhance extracurricular exercises, and it is recommended to choose some exercises with low difficulty to enhance your confidence.

Multiple choice questions are actually unscrupulous questions.

That is, in addition to plagiarizing others, all the methods that can be used can be used.

That is to say, the skills are all necessary.

It's usually an elimination method, where you get rid of what you definitely think is wrong, and then you analyze it, and then you come up with an option based on experience and calculation.

The second is to calculate: when you see a problem, treat it as a calculation problem, and compare the results you can get by yourself.

The third is to summarize some commonly used conclusions and data, which may save you a lot of trouble.

Fourth, it is to look at the expression of options, which generally involves everything in physics and chemistry, that is, it is more absolute.

The options are basically a bit problematic as long as you can veto them and that's OK

Fifth, in fact, it is necessary to read more books, to understand the principles of those theories, and to understand the typical examples in the books, which will also help a lot.

The high school entrance examination is about to be taken, you must have a good attitude, don't put too much pressure on yourself, in fact, you still have to be serious, careful and confident when you really take the exam.

It's good, don't be too nervous, I remember that when I took the exam, I didn't feel very good after the physics test, and I felt very good after the chemistry test, and I felt that I was the only student in Shaanxi Province with a perfect score, but after I came out, physics 118 chemistry 96, we had a full score of 120, and I was a little dizzy.

I've always been very stable in chemistry, and it's really strong, but it's just because I'm too careless.

So it's good to adjust your mentality The questions in the exam won't be difficult, at least they should be easier than what you usually do.

The choice is to do more questions to improve the accuracy rate, and unlike the calculation questions, there are often some questions that are more biased, so let's practice more! If you do a good job in the calculation questions, it means that your theoretical foundation is good, and I believe that it is very promising to get a good score in the exam, come on!

Personally, I think the book of the physics formula of the green card series is not bad, there are all the formulas from the first to the third year of junior high school, and it is recommended to buy a copy and take it home to read.

When doing the questions, carefully circle the key points, don't write it, forget it, check it, don't calculate the numbers, see the correct ones as wrong, first easy and then difficult, definitely good to get points, calculate the questions, write the formula well, sometimes the teacher deducts points Draw the picture first Take a pencil to draw a good drawing, although there is no paper score in physics, but you also have to leave a good habit I wish you success in the high school entrance examination You finish the exam in 20 days, I will take the test--

If you don't know how to do the question, actively ask the teacher and don't keep it.

First, first of all, we must master the knowledge in the books, and the teacher will understand a lesson when he talks about it, and there should be no dead ends.

Second, if you don't understand the content before, find a way to understand it, and ask your teacher or classmates.

3. Do more exercises, summarize similar topics, and find out the rules as much as possible.

Fourth, do not be afraid of hardships, do not be ashamed to ask, and if you have any doubts, understand them as soon as possible.

Listen carefully, think more, use it, and learn it live.
