Can anyone tell me that most of the knowledge in junior high school is useless?

Whether it is the current junior high school, the previous elementary school, or the future high school and college, not all the content learned has to be used, learning this lot of knowledge is not to master all the knowledge, but to be able to make the brain continue to be developed, people who have gone to school are always faster than the brains of people who have not been to school, that is, because learning can establish a large number of conditioned reflexes in the brain, a large number of learning, you can make the brain accustomed and good at establishing conditioned reflexes, if you do not learn, even if you do not participate in mental work in the future, It is also often disadvantaged in social life, and it is completely absurd to go to school for the sake of going to school, because the most important thing now is not the diploma, but a flexible brain.

No, the knowledge of junior high school is to lay the foundation for high school, and it is all for high school.

For example, if you learn plane geometry in junior high school, and the solid geometry you learn in high school often has to convert the solid geometry into a plane to find congruent similarity or something, if you don't learn plane geometry well, you can't deal with solid geometry. The same goes for algebra, if you don't memorize the formulas in junior high school, you won't be able to perform more complex operations in high school. And when the high school teacher corrects the paper, although he will not look too carefully at the conclusions you have obtained with his junior high school knowledge, you must write it correctly, otherwise when it comes to the later answers, you will be wrong because of the previous calculation, and the back is all wrong.

When you reach high school, you will know that although the process score is important, the teacher is in a hurry to see if the answer is correct, so junior high school knowledge is also very important.

However, if you have already decided to study liberal arts in junior high school, then you can allocate more time in physics and chemistry to geography, politics, and history in the future, and cultivate a sense of liberal arts in an interesting way.

If you study science, then the knowledge of junior high school is also very important, and if the foundation is not strong, the house will be shaky, and the exam ranking will go up and down at that time.

I'm from the past, and these are my own opinions. Hope it helps.

Elementary and junior high school is still useful, because it is the most basic, a lot of daily life to use, such as Chinese to teach you sentiment and the most basic speaking and writing, mathematics in life can be used to calculate some equations, etc., natural science gives you the most basic common sense of life, are still good, just because there are exams so let a lot of things learn for the sake of learning, rather than using it in practice, it is really a failure of education. But in your future work and life, you will find that the things you learned in junior high school are still very basic, and you must study them well. In addition, the high school school is a little useful, but the things you learn in college are useless.

Junior high school is the foundation, high school expands the foundation, college is useful for learning, if you don't lay a good foundation now, you will regret it in high school, and you will no longer work hard in high school, you will feel very difficult, so, at the beginning of junior high school, you must lay a good foundation step by step, those questions do not need you to think too far, if I ask you, is the arithmetic you learned in primary school useful? That's the problem! Those are knowledge if you have mastered them!!

That's not true.

The knowledge of junior high school is the foundation of high school knowledge, without the knowledge of junior high school, you can't learn high school at all, then high school is not good, what to do with the college entrance examination, and what will you do in the future?

Always, learning is a prerequisite for a better life in the future.

The knowledge of junior high school and high school is complementary to each other.

Now you must start working hard, first take the high school entrance examination, and then work hard.

It's really useless in society, but in high school, it doesn't work without junior high school knowledge, and you have to go step by step.
