How to learn mathematics? Can the college entrance examination be about 140?
Since I don't know which province and city you are from, I will give an example of the national volume 1 (the national volume without curriculum reform 1) as a reference. The total score of 1 is 150, so you need a lot of math ability to get 140! Then I will give you an analysis of how to get 140! The following are specific suggestions:

1, basic knowledge: do all the exercises in the math book first, in fact, some people will think it is very simple or unnecessary at all! However, after the college entrance examination over the years, all our teachers will say that many topics this year are the examination of basic knowledge, and how to acquire basic knowledge is the first kind of knowledge we come into contact with in textbooks! So first of all, do all the exercises at the back of the textbook. We need to look up questions that we can't do online, or go directly to the teacher's office to ask the teacher, or ask the students with good grades in the class. Anyway, we just want to know. If we really don't understand, we will copy the topic twice, and then put each step into the specific knowledge points in the book, which will be impressive. If we meet next time, it may be solved.

2, review the book: because the exercises at the back of the book are only a summary of each chapter, not as comprehensive as the college entrance examination questions! So after completing the above steps, you should choose a good review book! Personally, I think any book that simulates the five-year college entrance examination in three years is not bad, because many of them are sex tests in other provinces and cities. This kind of question has a test paper strictly controlled by the teacher, and many students have tested it. It will not be particularly bad, even if it is bad, it will not be surprisingly bad! I have the following suggestions for this book:

(1) First of all, after the teacher finishes a chapter, we should spare some time to practice the topic of the chapter every day. For example, after the teacher finishes the series today, we need to search what knowledge points the series will relate to the college entrance examination. Usually, we will know that series and functions will be examined (20 13 Sichuan Volume (Science) 23), series and analytic geometry by reading the test paper or the teacher's explanation. Let's sum up our learning ability and methods according to these situations (that is, we can't work out those series of questions by reading a test paper ourselves). What are the shortcomings and areas that need improvement? We will focus on this weak point!

(2) In practice, we should tear up all the answers. We took the practiced questions to our friends in class and asked them to help me correct them. We are determined not to look at the answers ourselves, we are thinking about what we see wrong. If we do it again, we will see the answer. If we don't understand the answer, we will go online to find teachers and classmates to answer!

(3) We bought this book and all the topics need to be done. Don't talk too much, there is no time. It can be finished in a little time every day. After finishing, we need to set up an error book to record our mistakes and correct them later! And try to read this review book twice before the second round of review!

If you get good results in the first round of review, then your second round of review will be relatively easy. Now we need to get the experience of the simulation questions we have done before to do the real questions. Why do you have to do real questions? Because the real questions are personally verified by our brothers and sisters, which is the admission standard of colleges and universities. There is nothing like real questions, so now I need to do all the real questions for three years. Why do we have to do it four times? Because I do it a few times more, I will have a deeper understanding of the mathematical problem-setting model and answering standards in our provinces and cities!

I have some opinions on the real questions: the topic setting of the first national volume is multiple-choice question 12, fill-in-the-blank question 4 and answer 6! The first two questions are generally two short-answer questions, solid geometry is sometimes three questions, followed by two questions, and the last question is sometimes three questions and sometimes two questions (usually two questions, depending on the conclusion drawn from the real question). Then we get 140, which means we can only subtract 10. Then we need to make at most one wrong question in multiple-choice questions (the last question is the most difficult and may be wrong). Fill in the blanks can't be wrong, the last question of the last question of the big question can be wrong, and everything else must be right. For multiple-choice questions and fill-in-the-blank questions, because they are on machine-readable cards, they are objective questions, right or wrong, but the big questions are different. It is possible that your conclusion is correct, but the process is incomplete and you will be deducted! Because the big math questions in the college entrance examination are graded according to the steps, at this point, we need to write out the whole process when reviewing, and the more detailed the better! You may think that simple questions are easy to read, but you haven't started to calculate, or even the writing process is just a rough idea but not very careful, then your college entrance examination is doomed to suffer, which may be far from your expected goal.

The above are the strategies and tactics when reviewing, but there are still many uncertain factors in the examination room, because the college entrance examination teachers are very strict in invigilation, surrounded by candidates from other different schools, and you don't know anyone, which sometimes gives people an inexplicable sense of tension. Try not to be nervous during the exam, because nervousness can easily make you lose your proper limit and lead to poor exam results. In order to solve this problem, you need to take the model test exactly according to the time of the college entrance examination one week before the exam, and never let the water go, even stricter than the college entrance examination! In this case, after the above review, you may achieve your expected goal. This is the experience given to you as an experienced person, and I hope it can help you! I wish you good grades in the exam, come on!
