Is it difficult to master physical chemistry in the third year of junior high school? Do I need to s

There is electricity in physics in the third year of junior high school, so it's a bit difficult to prepare.

Chemistry is mainly memorized, and I only took one multiple-choice question in the last unit of the high school entrance examination.

Chemistry is relatively simple in junior high school.

If you are physically speaking, you can look at it first.

It's not difficult, what you should preview is your previous knowledge, because the third year of junior high school integrates the previous things together and then deepens the difficulty, and then learns some new things, so the main thing when reviewing, the new knowledge will not be difficult in the third year of junior high school.

Physics is a bit hard, you should learn it during the holidays!

Let's focus on reviewing physics in the second year of junior high school! Chemistry can start with a simple memorization of the instrument and the experimental process.

Give me a point! Hee-hee.

Which is more difficult in junior high school, physics or chemistryMiddle School Physics

Middle School Physics focuses on the understanding of theorems, laws, and formulas, rather than memorization. There are few test points in junior high school physics, about 73 test points, but some test points are quite difficult, such as experimental and calculation questions in electricity, and calculation questions in mechanics.

For junior high school physics, it may be more important to cultivate problem-solving methods and form your own physics ideas, because high school physics is more difficult, and junior high school physics cannot be compared, maybe you have been excellent in junior high school physics, and it is very possible to fail in high school physics!

Middle School Chemistry

Junior high school chemistry is a science that studies the composition, structure, properties, and changes of matter, because there are so many knowledge points, it takes time to memorize. Unlike physics, no teacher will ever tell you how many test points there will be in chemistry for the high school entrance examination, because there are too many and too many for the teacher to count.

However, if you learn chemistry well in junior high school, you will feel that high school chemistry is also very easy to learn in high school, and as far as chemistry is concerned, junior high school and high school are very closely related, which is much better than physics.

Methods of learning chemistry in the third year of junior high schoolBe diligent in pre-studying

If you want to learn chemistry well in junior high school, you must first understand this course. Be sure to preview before class, in addition to reading the content of the new lesson carefully, you should also mark the areas you don't understand, and try to do the exercises in the textbook. In this way, with questions and difficulties, the efficiency of listening to the class will be greatly improved.

Take good notes

Learn to take notes. Junior high school chemistry is very simple, but the content is very complicated, and you must take careful notes in class, and at the same time, you have to spend time memorizing after class.

Have your own notebook. You can use three different colors of pens to record the questions, black to record the problem-solving process, and red to record the key points of the problem-solving.

1. Chemistry in the third year of junior high school is the foundation, which is a preliminary understanding of contact chemistry, which is relatively simple. But many times you have to learn it as a liberal arts, the basic valence, the chemical formula must be memorized, the equation does not need to be memorized, the equation is regular, and it is flexible to understand. As for phenomenal experiments, pay more attention.

Induction while learning, many of them are analogies. There is still the last month, take a good look at the book, many fragmentary knowledge points of chemistry are not reviewed by the teacher, only read the book to master. Do a few more sets of questions from previous years' high school exams, the types and knowledge points are the same;

Physics in the third year of junior high school is relatively added to electricity, which increases the difficulty on the basis of the second year of junior high school, but the knowledge is interlocking.

1) Memorize the formulas, and make the title of the chapter that mentions it will naturally reflect all the formulas in the chapter. This will help you feel the right thing and build confidence in your problem-solving.

2) Use it flexibly to learn physics (I think we should start with concepts).This will help you find a breakthrough quickly. You can read more about physics, physical phenomena in life.

3) Learn to review. Make regular summaries so that what you have learned is not easy to forget. And the third year of junior high school is a melting pot, and the final high school entrance examination is to test the comprehensive strength of students.

4) Practice more. To lay a solid foundation, the comprehensive questions are practiced in chapters, no difficulty, do not ask for difficulty, do some classic physics high school entrance examination finale questions, remember not to look at the master or cower in difficulty, to have perseverance and perseverance, if you really don't want to learn to seek help from the teacher.
