For a student with poor physical foundation. Your other science majors are not bad, except physics. My analysis is as follows:
1. When you learn knowledge, you only pay attention to the result, not the process. What do you mean? You learn by memory, not by understanding. Memory learning, learning physics is not good, you simply don't understand the essence and process. You think you just need to remember the formula, but you don't understand it, so be flexible. I don't know the specific analysis of specific problems.
For example, the teacher told you that the liquid pressure formula is P= density *g*H, and the solid pressure formula is p = f/s.
For you, you only know these two formulas, and your memory is really good. But have you ever thought that there is something wrong with the solid pressure P?
It is impossible to work out this formula from your memory. You need to change the solid pressure into another expression: p = f/s = f/(v/h) = mg/(v/h) = (m/v) * g * H = solid density * g * h.
(briefly explain: for regular solids, such as cylinders, rectangles, cubes ... as long as their volume formula is V=S*H,
You can deduce that s = v/h, for f, the pressure of a regular object is F=mg, and then substitute them into the formula of solid pressure, and combine m and v to get the solid density =m/v, and finally it is transformed. )
Have you thought about this? Can you do it from memory? Only by deeply understanding the meaning of each quantity in the formula and the application conditions of the formula can we change flexibly.
You are good at chemistry and English. It proves this point again. You just remember the result, but you can't apply it. You see, chemistry in junior high school is just memory and simple calculation. Without complicated calculations, you can learn chemistry well by memory. But physics can't, because it is closely related to life. You need to understand the principle and apply it to practice. Basically, every problem is a practical problem.
3. Improve your study methods. Your memory is good, which is both your advantage and your disadvantage. The advantage is that you can remember your grades quickly. You are good at English and chemistry and need a lot of memory. The disadvantage is that it is good memories that make you lose the opportunity to think. Most people will understand a formula in order to remember it. You just need to look at it and don't think about anything. Make you lose this important link in your study. For the study of knowledge, especially in a certain law, there will never be a word that is nonsense. Be sure to understand it word for word and never let go of any conditions. My suggestion is that it is better to know how many punctuation marks are in it. Of course, I mean understanding, not rote learning.
For another example, you must be familiar with ohm's law, but do you know it? In some places or situations, ohm's law does not hold. Do you know this condition? Can you tell me why? You shouldn't know (I guess)
4. Physics comprehensive learning method.
First of all, it is necessary to listen carefully in class. If you can't do it, do it, if you can't do it. No one can help you.
Secondly, you should have the habit of taking notes after class. After the teacher has finished, read the book by yourself, and then take notes by yourself. It must not be class notes. You should study the teaching materials and write your own notes. If you can understand and write notes well, it proves that you understand thoroughly.
Finally, the study of physics needs efficient study. You can't make the same mistake twice. Be sure to have your own wrong question bank. After reviewing the senior high school entrance examination, you did a lot of questions. Be sure to add the questions you did wrong for the first time to your wrong question bank. And always remember, ask yourself, why, where is wrong. Requirements: Every time you see a sentence in the wrong question bank, you should immediately recall where this question is wrong and why.
To do these things well, it is not difficult to learn physics at all, especially in junior high school, which has only a little content. You said you had finished your physics. My suggestion is that there is still some time before the exam. Read those textbooks carefully, take notes by yourself, and communicate with the teacher in time if you have any questions. Do exercises after class to strengthen understanding. Never leave your original religion, and never leave the textbook in the exam.
Once you have established this ability of learning and understanding, you can take any course. Even without a teacher, you can say that your learning ability is comparable to that of a teacher at this time. When studying science, we must pay attention to understanding, not just memorizing. If knowledge is simply rote learning, then you can only be regarded as an average student without any ability. Once you leave the exam, you can't study. In other words, if you have something to ask for leave and miss several classes, it will be too difficult for you to make up for it. But for a high-level student, I can learn well even if I don't attend classes for 3 to 5 days. There must be such people around you. Observe them carefully and communicate with them.
Finally, I wish you progress in your study. If you can do what I said and get into a good high school and a famous university, it shouldn't be a very air crash.
