Are all the mathematics, physics and chemistry knowledge in junior high school and high school textb

Of course, that's not the case, and when you get to college, you'll understand that many things have limitations and aren't necessarily right. It can only be said that at the secondary school level, it is true under a certain premise.

Many things are right in junior high school, but not in high school or college;

And some things are true in Gaozhou, not in college.

It's like the math we learned in the first grade of elementary school.

1-3=-2 doesn't work, but it's equal to -2, and there's just a limit to what we can learn.

I don't dare you to ask this question, so I dare to say: It is better to believe in books than to have no books. Obviously, it is impossible to be right in all books, but it is never all wrong. Therefore, what we learn is useful, not to mention going to university, it may at least exercise our thinking.

For example, in middle school, you think that combustion is in oxygen, but in high school, you will learn that carbon dioxide can also support the combustion of magnesium. This is just a step-by-step way of learning, after all, you can't accept it if you are just instilled in it all at once! Hehe.

Because the situation and environment of the study are different, there is no absolute right or wrong.

There must be mistakes, but you must also learn, otherwise you will not be able to step into the threshold of the university, only by entering the university, you will have a closer opportunity to correct their mistakes, the future belongs to you young people, study hard.

Of course not, listen to the class well, and the teacher will point out the wrong place.

Mathematics: Compulsory 1, 4, 5, 3, 2 (usually in this order) Electives 2-1, 2-2, 2-3, (4-4, 4-5 will be mentioned, not necessarily in the textbook) Physics: Compulsory 1, 2.

Electives 3-1, 3-2, 3-5 (momentum), 3-4 (vibration, light), 3-3 are not necessarily on;

Chemistry: Compulsory 1 & 2.

Electives 5, 4, 3 (usually in this order).

Biology: Compulsory I, II, III;

Elective 3,1

It doesn't seem like there are new classes in the third year of high school, and I haven't heard of new classes in the third year of high school.

The reason why some students feel that mathematics, physics and chemistry are more difficult to learn is mostly because they have not found the right learning method. As long as you understand a formula, you can solve a lot of problems, so what are the ways to learn mathematics, physics and chemistry?

First of all, mathematics should do more exercises, connect the learned knowledge with the exercises, and review and consolidate the basic knowledge points; The learning of physics can be divided into several independent parts, such as force, heat, electromagnetism, light and atoms, and a corresponding learning method is formulated for each part, which helps to clarify the concept and improve efficiency. The study of chemistry is mainly to master the knowledge points and basic theories in the book, supplemented by high-quality exercises, and the laboratory course is also the content of the college entrance examination, which needs to be mastered.

1. Do more questions

The most useful way to learn mathematics, physics and chemistry is to brush more questions, unlike politics and history, as long as you memorize it, you can get high scores.

We are also very particular about brushing questions, we try to do some questions corresponding to the daily course, you can do the roll paper issued by the school, you can also buy some related practice questions, brush more questions than others, your score may be one point higher than others.

2. Refer to auxiliary materials

Most students will feel that the content learned in the textbook is difficult to understand, and the class cannot keep up with the teacher's rhythm, I don't know if you remember that in junior high school, students will use the application to fully understand, and then combine the textbook to listen to the class, so that it will be easy to keep up with the teacher's lecture rhythm, and the content learned can be understood.
