1. Remember the concept clearly and lay a solid foundation.

Never ignore the most basic concepts, axioms, theorems and formulas, especially "indefinite multiple-choice questions", and distinguish right from wrong by clear concepts. If the concept is unclear, you will feel ambiguous and eventually lead to the wrong choice. Therefore, we must sort out the concepts we have learned and deepen our impression through reading and copying, especially the concepts that are easily confused, so as not to leave hidden dangers.

2. Concentrate on the weakness.

Everyone has his own "weakness". If your weakness is involved in the exam, it will definitely be your most painful. Therefore, we must concentrate our superior forces and fight a beautiful annihilation war through short-term special study to avoid becoming a "cripple."

3. Record the wrong questions to avoid repetition.

As the saying goes, "once bitten, twice shy", but students often fall into similar or even the same "trap" again and again. Therefore, I suggest that you should record the wrong questions in time when doing the questions at ordinary times, think about why you are wrong, and pay special attention to what in the future to avoid unnecessary loss of points. After all, in the senior high school entrance examination, "every point counts" and you can't lose a point.

4. Contact before and after.

When doing problems, we should pay attention to discovering the internal relations between problems, and never "do stupid things". When doing similar topics like before, we should find the law through comparison, penetrate the essence and achieve the effect of "analogy" In particular, the method of adding auxiliary lines to geometry problems is very regular, so you should remember it especially when doing the problems.

5. Do the questions properly and skillfully.

Hard work, a large number of counseling books have been done but rarely improved, which is the misunderstanding of doing the problem. Mathematics needs practice and a lot of questions, but we should "bury our heads in solving problems, raise our heads and think", pay attention to the ideas, methods and skills of solving problems, and "work hard" and "be clever". Time is the most precious thing in exams. If you master good ideas, methods and skills, you can not only solve problems quickly, but also make mistakes easily.

Second, the examination room should straighten out four relationships.

1. Straighten out the relationship between examination and problem solving.

Some candidates do not pay enough attention to the examination of questions, are eager to achieve success, and rush to write, so that they do not fully understand the conditions and requirements of questions. As for how to dig hidden conditions from the problem and stimulate the thinking of solving the problem, it is even more impossible to talk about it, so there are naturally many mistakes in solving the problem. Only by patiently and carefully examining the questions and accurately grasping the key words and quantities in the questions (such as "at least", "a > 0", the range of independent variables, etc. ), and get as much information as possible, in order to quickly find the right direction to solve the problem.

2. Straighten out the relationship between difficult and difficult questions.

After you get the test paper, you should read the whole volume. Generally speaking, you should answer in the order from easy to difficult, from simple to complex. In recent years, the order of examination questions is not completely difficult. When answering questions, we should arrange the time reasonably. Don't fight a "protracted war" on a stuck question, which will take time and won't get points, and the questions that can be done will be delayed. In recent years, mathematics test questions have changed from "one question to many questions", so the answers to the questions have set clear "steps". Wide entrance, easy to start, but difficult to go deep and finally solve. Therefore, seemingly easy questions will also have the level of "biting hands", and seemingly difficult questions will also be divided. Therefore, don't be timid when you see the "easy" questions in the exam and the "difficult" questions of new faces. Think calmly and analyze carefully, and you will definitely get the score you deserve.

3. Straighten out the relationship between speed and accuracy

The word "quasi" is particularly important in the current situation of large amount of questions and tight time. Only "accuracy" can score, and only "accuracy" can save you the time of examination, while "quickness" is the result of usual training, not a problem that can be solved in the examination room. If you are quick, you will only make mistakes in the end. For example, it is not difficult to list the piecewise solving functions of an application problem, but quite a few candidates have miscalculated even one function in their haste. Although the follow-up questions are correct in thinking and take time to calculate, they hardly get points, which is inconsistent with the actual level of candidates. Slow down and be more accurate, and you can get a little more points; On the contrary, if you hurry up and make mistakes, you will not get points if you spend time.

4. Straighten out the relationship between "doing" and "dividing"

To turn your problem-solving strategy into a fractional point, it is mainly expressed in accurate and complete mathematical language, which is often ignored by some candidates. Therefore, there are a lot of "yes but no" and "yes but incomplete" situations on the test paper, and the candidates' own evaluation scores are far from the actual scores. For example, the "skip" in geometric proof has caused many people to lose more than 1/3 points, and the "substitute proof with pictures" in algebra, although correct or even clever in solving problems, has a poor score because it is not good at accurately translating "graphic language" into "words"; Another example is the image transformation of trigonometric function. Many candidates "have ideas" but can't say clearly, and there are not a few people who deduct points. Only by paying attention to the language expression of the problem-solving process can we grade the "can do" questions.

In a word, the key to improve math performance is to grasp the overall situation, highlight the key points, grasp the foundation and improve the ability. Review the knowledge learned in junior high school, highlight the main knowledge, strengthen the review of teaching priorities, systematically sort out the knowledge learned and integrate it into a knowledge system. Understand the basic mathematical thinking methods and strategic thinking of analyzing and solving problems; Master the law of solving problems, draw lessons from experience and improve the quality of mathematical thinking, and you will definitely become a top student in mathematics.
