First of all, junior high school mathematics is more difficult than chemistry and physics, and the math score in senior high school entrance examination generally accounts for 120, which is 20 points higher than physics and chemistry. But personally, in the eyes of junior high school students, physics and chemistry are much more practical than mathematics.

Then don't talk nonsense. Tell LZ how to learn math and physics well according to personal experience. I guess LZ should be a junior two student.

First, it is very important to learn these two things well: preview before class, listen carefully during class and review after class, but I think the key is understanding and efficiency in class. Don't think that I don't understand in class, just think after class. If you don't understand anything, you must have the cheek to ask the teacher. Don't be afraid that others will laugh at your own problems and think you are stupid.

Second: For example, when the teacher talks about three math problems in class, and he finishes the second one and prepares to talk about the third one, if you still don't understand the second one, then don't teach yourself and ignore the teacher's explanation of the third one. What you should do correctly is to listen to the teacher and continue to talk about the next question, otherwise you will accumulate more incomprehension of the question.

Third, we should keep the good habit of previewing before class and reviewing after class. The phrase "a good memory is worse than a bad pen" should be done not only by taking notes in class, but also by previewing yourself before class and drawing formulas and sentences that you think are important with bright strokes. When reviewing after class, it is suggested to buy a notebook and write down important formulas, even if they are in books, so as to deepen your memory.

Fourth: I think the last and most important thing for the time being is to finish the homework assigned by the teacher and do more exercises. Where did the examination questions come from? Numerous examination room experiences tell me that most of the examination questions are similar to the exercises given by the teacher. In this way, only if you do it, you won't feel that the exam is in a hurry. Remember! Practice, practice. Practice again.

I am also a junior high school student, and I caught a cold at home today. When I was bored, Baidu was deeply moved to see LZ care so much about learning. I hid these experiences from you and hoped to adopt them. If you don't understand, you can chat privately and add me QQ. . .
