The college entrance examination is only 100 days away. How to improve math scores?
First, be proactive and clear about the direction.

After nearly a year of review, most schools should have completed the first round of review and model examination, and entered the stage of special review or comprehensive training. The biggest feature of this stage is that teachers talk less and do less homework, but there are more exams and more time for self-review. This is a test for students who are used to being led by the nose by teachers. At this time, we can't be at a loss to find the direction, nor can we let it relax completely. It's a good thing to have more free time. In addition to following the teacher in a normal review class, it is just right to calm down and analyze yourself, make a comprehensive clean-up of what you have learned, find your own strengths and weaknesses, accurately position yourself, and clarify what you should strengthen and make up for in the later period. Remember, you can't find the north without clues. So, what should we do most in the last month?

Second, return to the foundation and build a network.

In the last month, the first thing to do is to pay attention to the review, understanding and memory of basic knowledge. Don't just dive into the sea of questions and blindly do comprehensive questions, simulation questions and tackling key problems. Every candidate should understand that the middle and low-grade questions are the real results in the college entrance examination, and the middle and low-grade questions are based on textbooks, so we need to return to textbooks and return to the foundation. Of course, this regression is not to read the book from beginning to end, but to search for memory first, including every concept, example, annotation and figure, to accurately understand and remember knowledge points and see if there is any knowledge missing, that is, we often say that we have seen movies; Then carefully analyze and study the structural relationship, logical level and mutual relationship between knowledge points, classify them, establish a knowledge network, connect isolated and single declarative knowledge in the new curriculum, turn it into procedural and strategic knowledge, form a system and plate, and thus grasp it as a whole. For the knowledge encountered in the comprehensive examination, we must consult the teaching materials in time, find the crux of the problem, and completely remove the obstacles. This is especially important for those students who have poor foundation and weak concept theorem and know everything at a glance, but they don't know anything when they close the book.

Third, check for leaks and fill gaps, and sum up and improve.

After the model test, teachers should summarize the students' test situation and remind everyone of the problems that should be paid attention to in the later review. But this summary is for the whole class, and each student should make some summaries for himself. Specifically, I think it is most important to pay attention to misjudged cases and make up in real time. It is the biggest regret of many candidates every year that those who can get points don't get points. The misjudged case is an important wealth, which directly reflects our lack of knowledge, thinking and methods. In the final sprint stage, candidates are advised to collect and sort out the previous big test papers and the in-class test papers in the comprehensive review, and set up their own special error question bank, especially for those typical mistakes caused by poor concept understanding, poor knowledge and memory, imprecise thinking and improper application of methods, we must collect comments, point out the reasons for the mistakes, and read regularly to remind ourselves to ensure that the same mistakes will not be made again in the college entrance examination. Don't blame all your mistakes on your carelessness, but try your best to solve them.

Fourth, focus on attack and be radical.

In the final review stage, in order to ensure the maximum improvement of learning effect in the shortest time, we can't do a lot of repetitive useless work, so candidates should learn to grasp some typical problems, summarize and review them, make full use of the topics, fully excavate them, concentrate on fire breakthrough, and truly understand the knowledge, methods and principles. For example, when proving the monotonicity of a function, the definition should be used to complete the step of "difference-deformation-comparison"; When judging the parity of a function, we must first judge whether its domain is symmetrical about the origin; The program of "one positive, two definite and three equal phases" should be followed when finding the maximum value of a function with basic inequalities. Triangular transformation (changing angles, names and degrees) is the core of solving trigonometric problems, and the key to solving the problem of trigonometric function evaluation or simplification lies in "grasping the formula clearly and grasping the transformation secretly"; When dealing with the midpoint of the chord of a conic curve, it can generally be summarized as a model of "setting (linear equation)-substitution (entry)-elimination (element)" or "setting-substitution-subtraction"; When dealing with the positional relationship between a straight line and a conic curve, we generally follow the thinking chain of "simultaneous elimination discriminant (Vieta theorem)". Under the guidance of the teacher, candidates can decide some main lines and themes by themselves. For example, in mathematics, functions, sequences and inequalities can be taken as the main lines, and special topics such as the positional relationship between straight lines and planes, straight lines and conic curves, trajectory problems, algebraic proof problems, the solution of application problems and exploration problems, the application of four mathematical thinking methods, and the excavation and utilization of implicit conditions can be strengthened. Students can make these questions into cards and read them at any time. Then we should choose some typical problems to do, reflect after solving them, summarize the methods and skills of such problems, extend the changes of typical problems, and promote the series of knowledge and the sublimation of methods.

Five, familiar with the outline, learn to control the paper.

"Examination description" is the basis of the college entrance examination proposition, and it is also the knowledge requirement for candidates. Although the teacher will definitely emphasize it when reviewing, students had better study the exam outline carefully. Moreover, the syllabus varies from place to place, and textbooks and review notes are compared one by one to see if they have been implemented and ensure that there are no omissions. In particular, we should attach great importance to the contents adjusted in the syllabus, make clear the requirements, and improve the pertinence and effectiveness of review. At the same time, the form, type, test time, score and so on of the test paper should also be clear. In addition, in the last one to two weeks, you can do two or three minutes of local college entrance examination papers, warm up before the exam, understand the spirit of the college entrance examination, be familiar with the examination mode, and experience the examination atmosphere, but you must not do too difficult papers to avoid unnecessary mental burden.

On the other hand, combined with teachers' usual comprehensive examinations, we must strengthen the training of test paper control ability. When taking the exam, we should follow the principle of "easy before difficult, small before big", never relax on the basic questions, and ensure that the "easy to see" questions are "right to do"; For intermediate questions, we should calm down and work hard enough to prevent "meeting but not right, right but not complete"; For difficult problems, we should think calmly, analyze carefully, and start to solve them if we have the ability. Otherwise, you should try to write out the relevant basic formulas and initial steps, so that you can score more points. You can temporarily "give up" the problem that you can't attack for a long time, and prevent the situation that "the problems in front can't be attacked for a long time, and the problems behind are too busy to take care of". It is easier to score when you try to solve the remaining problems after your thoughts are smooth. In the process of answering questions, we should pay attention to standardization, ensure that the problem-solving process is rigorous, standardized and complete, and eliminate unnecessary hidden points, such as avoiding "jumping questions" in solid geometry and "trying to prove" in algebraic argument. It should also be noted that online marking also improves the requirements for candidates' writing ability. Therefore, it is suggested that candidates should focus on the standardization of answering questions and writing when approaching the college entrance examination, rather than focusing on difficult problems to improve their scores.

Sixth, adjust the mentality and take the exam easily.

Before the big exam, most candidates were very nervous, but some of them were completely relaxed. Excessive tension and complete relaxation are abnormal, which will affect the normal performance of the exam. The author is not a psychologist, and only gives the following simple suggestions to students who are too nervous: 1. Correctly understand your own level, strength and reasonable expectations. This is difficult to do, but it is actually very important. ) 2. Make unrealistic comparisons to reduce the pressure on candidates. Pay attention to physical exercise, ten minutes at a time, and be energetic all day. 4. Pay attention to rest and combine work and rest. 5. Supplement nutrition, mainly light, reasonable diet, and replenish the spirit.

I believe that only a peaceful mind can bring efficient review and higher examination status. The last 30 days, though not long, are crucial. It can be said that it is common for students of the same level to have a difference of 20-30 points in college entrance examination results if they grasp well, depending on who is good at grasping opportunities. A penny a day is not for fun.

Hope to adopt, thank you.
