I have a method but it is not suitable for everyone, that is, you study in the mode of a student in the third year of high school, the kind of books that are always reviewed, look down on the knowledge points from a height, don't bury them in the memory one by one, it is best to organize a treemap pattern, so that you will find the common point of many chapters in physics, and their difference is that the formulas used are different, this college entrance examination is very easy to use, my physics is more than 110 (120 full) chemistry is not easy to say, I am also very watery.

Specifically find a complete time, such as evening self-study, and spend two hours completing a physical section, or a type of problem. Such a solution one by one can succeed step by step! This method is used in mathematics, physics and chemistry.
You must know that you don't know that, so you can learn that.
-
Understand the concepts, read more example problem analysis, and then practice more to achieve mastery of problem solving methods and problem solving format writing.
-
Chemistry must be memorized, read more textbooks, do more questions, find more teachers to answer questions, or find a one-on-one tutor to learn well.

Personally, I am an undergraduate student majoring in chemical engineering. I'm going to talk about chemistry. To study chemistry, you must first understand the table of elements, the properties of elements, and simple reactions of matter.
To put it simply: 1-2-3 One atom, one molecule, one molecular formula Slowly expand your learning! Pay attention to the laws between the elements.

If you can't understand and memorize it, if you want to do well in the college entrance examination, you have to do things that others can't do......

Physics is a little difficult, but you need to know that the geometry of the conditions is good, and chemistry is nothing to memorize, and mathematics is nothing to learn well.

Hello, in fact, physics and chemistry are similar when they are said to be similar, and they are not similar when they are not similar, especially in high school.
High school physics is mainly modeling, remember that the teacher explains a few models, and set the model formula during the exam, and it will come out.
However, chemistry is actually more similar to biology, there are many knowledge points in chemistry, the content is complicated, it is difficult to be a point by point, modeling, that is, the knowledge points are scattered, so if you want to master the skill, it is slightly more difficult to master.
In high school chemistry, it is necessary to learn to listen to lectures well, carefully organize your notes after class, review them in time, and do more questions, so as to be proficient in the knowledge points of the book.

I think you may have a few reasons for not doing chemistry well in high school. First, your chemistry foundation in junior high school may not be very good. Second, I am not interested in high school chemistry. Third, the learning method is incorrect. Four. You don't understand when a chemistry teacher teaches a lesson.

There are many physical and chemical formulas, abstract, but they are more systematic, pay attention to the summary and induction of learning methods, there will be a great improvement, more questions and answers, I feel that the first and second laws of thermodynamics are very easy to learn! What is the Urals in the back, what chemical potential is too abstract, and the answer is Raoul's law, and Henry's law, pay attention to summary and induction, and later study phase diagrams, and use to ask questions about halfway monks, halfway monks, ordinary chemistry has not yet been learned, it is worth learning this, I feel too hard! The rest of my class learned generalization.
The physics thing, the most important thing to draw, a lot of known quantities come out of the graph. >>>More

(1) sharpening the knife is not a mistake to chop wood, the study of physics, first remember the formula, the formula is a tool for solving the problem, the formula can not be remembered, many problems are equal to "0" generally you can only remember the basic, other too complex temporary use in the use of the basic formula to push out. In the past, I had to summarize the formulas for a period of time, and organize and memorize all the formulas and some rules that I had gained from experience to use to solve problems. >>>More
I don't know what your situation is, but personally, I came to the United States at the end of my freshman year of high school, and then my AP Chemistry and AP Physics were both A's when I was junior, and I learned very easily, if you go to school in China and you can usually get 70 or 80 in exams, there is no problem, Americans think they are difficult, mainly because their understanding is very slow, so they can't understand a question for a long time, like you use the sea of questions tactics in China to pile up, It's so familiar with the formula and the like, so you don't have to worry about it. >>>More
Physics lies in frequent calculations to achieve the flexible use of formulas, chemistry and biology are a bit more associative in liberal arts, geography is better said, and it is perfect to see the map to a certain point.
