For your own weaknesses, for the key difficulties of the discipline, how do we know that you can't do it, you have to rely on yourself for everything!

Mathematics is mainly the algebraic system and the geometric system, which are more important to study physics and chemistry together, and do more experiments.
-
Set three separate times for yourself every day, math in the morning, chemistry in the afternoon, and physics in the evening (according to your interests). But don't just focus on one subject.
1. Write down all the formulas of the three subjects on a piece of paper neatly, stand them on a table or wall (preferably a place where you will always be able to see them), and look at them often to deepen the impression.
2. Do at least one question a day (one for each subject) to be more classic, preferably not too difficult, but the type that can often be seen in exam tests. There must be an answer, the kind that is very detailed, and after you finish writing it yourself, don't count it first. Look at the detailed explanation, follow his train of thought to think for yourself, compare the difference between the two, there are questions to mark and ask the teacher, the teacher likes to ask the students very much, but you have to remember the text.
3. Set a goal for yourself, how much to take in each subject and how much to improve.
4. Make a workbook for each subject, write down the questions you have done that you think are very valuable and the answers, and flip through them before each exam.

1 5 study in the morning and afternoon, play while dreaming, study in the morning and play in the afternoon 6 7 study in the morning.

I only listen to lectures in class, and I don't know how to ask my classmates after class.

It is recommended to make up for biology and mathematics, it is easy to get points in the biology college entrance examination, so once you lose points, you will be opened up the gap, mathematics is the main course, and the score accounts for a large proportion. The physics college entrance examination is not easy no matter how simple it is, and it is not easy to get a high score, so it is recommended to keep up.
-
Many of the knowledge points of biology need to be memorized, and I suggest that you can read a book before class or bed, it is very useful.
-
As long as physics, chemistry and mathematics do not pull points, biology is easy to make up, first of all, you must know where you have problems in biology, and then prescribe the right medicine. Let me tell you some of my experience, there are more biological knowledge points, it is really difficult to memorize one by one, and it is easy to remember, so at this time you should memorize through practice questions, ordinary knowledge points as long as a small amount of questions to strengthen your understanding, if it is the key, then it is recommended to strengthen the amount of training, just start to do a simple foundation, and after you really do it, you can add a little difficulty to improve, as for how deep the difficulty is, ask your teacher is the best. This is my own experience, and I hope it can be helpful to you.

Biology is the liberal arts in science, remember more, and do more questions

As for physics, as far as a single subject is concerned, the three basic concepts should be clear, the basic laws should be familiar, and the basic methods should be proficient. In the process of learning physics, it is very useful to summarize some concise, easy-to-remember and practical inferences or assertions to help solve problems and learn physics well.
To do the questions independently, you should do some questions independently (meaning not relying on others) and with quality and quantity. Solving problems independently, sometimes slowly, sometimes detours, but this is the only way to success.
The physical process should be clear about the physical process, and there will inevitably be hidden dangers in solving the problem if the physical process is not clear. Regardless of the difficulty of the topic, try to draw as much as possible. Drawing can transform abstract thinking into figurative thinking and grasp physical processes more precisely.
With graphs, state analysis is fixed, dead, and intermittent, while dynamic analysis is alive and continuous.
Listen carefully in class and don't get distracted.
The notebook class is mainly for listening to lectures, and there is also a notebook where there are some things to write down. Knowledge structure, good problem solving methods, good example problems, things that you don't understand well, etc., should be written down. After class, I also have to organize my notes, on the one hand, to "digest well", and on the other hand, to supplement my notes.
Study materialsLearning materials should be well kept, classified, and marked. The study materials are categorized into practice questions, test papers, lab reports, and more.
Time is precious, and without time there is nothing to do, so be careful to make the most of it, and using time is a very masterful art.
To learn from others, we should learn from others with an open mind, learn from our classmates, learn from the people around us, see how they learn, and often communicate with them "academically", teach and learn from each other, and improve together, and we must not be self-righteous.
Knowledge structure should attach importance to the knowledge structure, and it is necessary to systematically grasp the knowledge structure, so that the scattered knowledge can be systematized. It is as large as the knowledge structure of the whole physics, as small as the knowledge structure of mechanics, and even down to the chapters, such as the knowledge structure of statics, and so on.
Mathematics is so important for learning physics that calculations depend on mathematics. Learn mathematics well and make good use of mathematics as a powerful tool.
Physical activity: A healthy body is the guarantee of good learning, and vigorous energy is the guarantee of high learning efficiency.

More than a month of bad supplements in physical chemistry, you can do a little bit without opening the skylight, this is okay, but if you want to say that your goal is to reach the class average, then it's a joke. Therefore, the strategy is very simple, get more points, based on 0 points, take one more point is one point, do the questions directly, each one will not know, to figure it out, the difficult ones to give up directly, and only memorize the formula to memorize the concept. Classmates, you see that you are a comprehensive exam, right?
As a person who has come over, I can only say, don't be too demanding of yourself, if you can get one more point, it is a point, and the effect is better.
-
Consult with the teacher and do more questions on the basis of what you already have.
-
Chemistry is a liberal arts subject, you can read more books, memorize more equations and other knowledge points, and learn to summarize better. You can do more questions from previous years. Physics can be divided into modules and modules, solved one by one, physics needs to do more questions, understand the question type and solution mode, and do more questions can be summarized.
-
Read these knowledge points first, let the brain have a little impression, and then sort out the important ones, just remember the calculation formulas in physics, which is very useful.

I still have 40 days to take the college entrance examination, what should I do if I don't get into the first book, and I don't want to go if I get into the second book!! Ask for advice.
It's still too late, but it depends on your child's level. How bad is "bad"? If you don't know it by a large margin, it's a bit difficult to tutor at this time, if it's just a partial incomprehension, find a teacher to give him a penetration, and do more questions to make up for it. >>>More
Chemistry is the science that studies the properties, composition and changes of matter, while physics studies the essential composition and principle of matter, which is different from chemistry.
There is not much connection between junior high school and high school, so I think you should start from high school, mathematics and physics I think it's about the same, first read books (including reference books), see the definition, some information books are still very good, and then there are example problems, I am now in my third year of high school, physics is generally about 90 points, not low, the main thing is that it is very important to think by yourself, see a question first to clarify the idea, to dare to write, physical schematic diagram (mechanics, or kinematics) is very important, and then the different categories of questions will do some. Mathematics and physics are almost the same, the main thing is that you dare to write, don't look at it and don't do it. Some questions are calculated, and there is a feeling of "the mountains and rivers are full of doubts, and the willows and flowers are bright and another village". >>>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
Are you a freshman in high school? It is recommended that you choose Physicochemistry, Biology. >>>More
