It should be ok. I talked about the specific method in the previous one.
To repeat: 1Have the confidence to learn well. Many people are not good at math, and the direct cause is a lack of confidence. One or two failures create stereotypes.
2.Read the textbook carefully and think carefully about the meaning and implication of each sentence (e.g., why is this conclusion correct?). What definitions, theorems are needed? It is necessary to clarify the basis for each step, especially the proof questions.
3.Do the questions appropriately. After completing the problem, you must think: What kind of math knowledge is used in this problem? How did they fit together? Is there any other way? Compare the pros and cons of the method.
4.Don't throw away the finished questions, gather them together and read them often. Compare the similarities and differences between different questions.
For example, knowledge points, similar topics. In my experience, I should spend at least 5 15 minutes reading each chapter and each unit test every day and recall the practice. It may take a long time at first, but over time, it becomes clear at a glance.

It's just entirely possible, but it depends on the individual, and there are people who learn science and math with just a textbook.
But it requires good comprehension and summarizing skills. In fact, there are only a few types of questions in high school mathematics, if you only use one book of materials, the amount of exercises is relatively small, you should pay more attention to the summary, and pay attention to the flexibility of encountering the same type of questions again in the future.
Many liberal arts girls are not as good as boys in terms of logical ability, and mathematics is a science subject, so it will be of great help to treat it with a scientific mindset and pay more attention to summarizing.

Yes. You only need to get through the textbook and a textbook, and if you have too much information, you won't be able to find the point.

Yes, it depends on how you learn.

A university is a type of institution that implements higher education, including a comprehensive university, a specialized university, and a college, and is an organization with unique functions, and is an institution of higher learning that is interrelated with the economic and political institutions of society and that is conducive to the inheritance, research, integration, and innovation of advanced scholarship. It is not only the product of the development of human culture to a certain stage, but also on the basis of long-term school practice.
Through the accumulation of history, its own efforts and the influence of the external environment, the university has gradually formed a unique culture, and the mission of the university under the control of the university philosophy requires the university to cultivate students who are first and foremost noble and educated. This mission refers to cultivating students' complete personality, purifying students' minds, cultivating students' conduct, and exercising students' ability to criticize things.
University culture is based on knowledge and its disciplines (majors), which requires universities to focus on the future and the truth, become a highly decentralized organism, take the cultural (academic) mechanism as the leading mechanism of its own operation, and take rationality and academic value as the basic value of its own pursuit.

It is recommended to do school homework and past college entrance examination questions first. In the sprint for high scores, there are some of the more difficult questions in the post-class questions, specifically Group B and Group C.
My math teacher in my freshman year of high school said that ten years ago, if you got all the exercises in the book right, you could guarantee 90 points out of 150 in the standard paper. But now, getting all the exercises in the book right is only guaranteed to score 70 points.
But that's not to say that it's useless to do post-class questions. When I was in high school, I once heard an ancient god-level coach in Jiangxi Shujing say that when the college entrance examination questioner was locked up to solve the question, the most read was the high school mathematics textbook, and the proposition person in some provinces was allowed to bring into the place where the question was asked, and even only high school mathematics textbooks and playing cards, and the reference books could be restricted. In other words, the college entrance examination questions come from the textbook, but they are different from the textbook.
This means that in terms of question style, after-class questions and college entrance examination questions are not the same way, and the meaning of the after-class questions in the impression is obvious, and a few sentences explain what people do, but the specific implementation method may be difficult. The college entrance examination questions will not be so straightforward in the meaning of the question, there may be some detours, there may be traps, you need to interpret the meaning of the question from an obscure form to a popular form, but once you understand what this question makes you do, you will find that the specific implementation method may be a routine that you have used many times, and you can apply the test-taking routine taught in school to solve this popular form.
To sum up, in most cases, the after-class questions are easy to review and difficult to solve. The college entrance examination questions are difficult to review and easy to solve. Of course, the post-class questions here refer to the more difficult ones in the post-class questions. The college entrance examination questions here refer to the first 120 points of low, medium and difficult college entrance examination questions.

Don't stick to the edges? Who said this, it's just too sidelined.
Take, for example, calculus, the core of mathematics in college.
What is the basis of calculus? Functions, Limits & Continuous! Among them, functions and continuities are the focus of high school, and the first chapter of calculus is about functions, limits and continuities.
For unary function differentiation and multivariate function differential calculus, the derivative is quite important in high school, and of course it is deeper in college.
For the integration of unary functions and the integration of multivariate functions (including multivariate quantification-value function integration and multivariate vector-valued function integration, what?) Does it have something to do with vectors? Therefore, the vector of high school is also very important) that penetrates a lot of high school knowledge, what trigonometric functions, Qiao Kai Shi is inseparable from functions in short.
There are also infinite poles, differential equations, etc., it is unimaginable to learn these knowledge without high school mathematics, and in general, high school mathematics plays a very important and indispensable basic role in college mathematics.

The examination of mathematics is mainly based on the basics, and the difficult problems are only synthesized on the basis of simple problems. Therefore, the content in the textbook is very important, if the knowledge in the textbook cannot be mastered, there is no capital to touch the class.
1. For the content in the textbook, it is best to preview it before class, and the targeted practice questions after class must be done carefully, not lazy, and you can also repeat the class example problems several times when reviewing after class, after all, take good class notes when you are in class. "A good memory is better than a pen". For the solution of mathematical, physical and chemical problems, it is not enough to rely on the general idea in the head, but only after careful pen calculation can we find the difficulties and master the solution method, and finally get the correct calculation results.
2. Secondly, we should be good at summarizing and classifying, looking for commonalities and connections between different question types and different knowledge points, and systematizing the knowledge we have learned. To give a specific example: in the function part of higher algebras, we learned several different types of functions, such as exponential functions, logarithmic functions, power functions, trigonometric functions, etc.
But if you compare them and summarize them, you will find that whatever kind of function you need to grasp is its expression, image shape, parity, increase and decrease, and symmetry. Then you can make the above contents of these functions in a big **, and compare them to understand and remember. When solving problems, pay attention to the combination of function expressions and graphs, and you will definitely get much better results.
3. Finally, it is necessary to strengthen after-class practice, in addition to homework, find a good reference book, and try to do as many practice questions as possible in the book (especially comprehensive questions and application questions). Practice makes perfect, so that you can consolidate the effect of classroom learning and make your problem solving faster and faster.
