Three-speed mathematics
Ability+skill to improve math scores in the shortest time. In the busy high school study and intense college entrance examination review, maybe you are busy with a lot of knowledge review, maybe you are entangled in endless problems, maybe you are still worried about a series of problems, maybe you are still depressed about the unsatisfactory results of exams and model exams. However, I don't know if you are busy doing the problem. It's not that you are not strong enough, but that you are not familiar with how to take the exam. The ultimate goal of our review is to improve our exam results, which can be roughly divided into two ways: one is to improve the overall quality and ability of mathematics and better control the exam; The second is to be familiar with the examination characteristics, master the examination methods, and give full play to their existing potential and level. If we say that in the review, which of the above two methods can improve the test scores in the shortest time? For the former, it is the comprehensive ability that we need to accumulate throughout high school and even before. The improvement of this ability takes time and accumulation, and the improvement is limited in the short term; Knowing and mastering the latter's ability is very obvious for the rapid improvement of test scores in a short time. Moreover, in general school education, we often attach importance to the former and ignore the latter. We can use the following equation to explain the relationship and function of the above two. First-class math ability+first-class exam methods and skills = first-class math ability+second-class exam methods and skills = second-class math ability+first-class exam methods and skills > In fact, the mastery of exam methods and skills by second-class students generally includes the following aspects: First, be familiar with exam questions and arrange the time for doing them reasonably. Actually, it's not just a math test. Before taking any exam, we should be clear or clear about several questions: the length of the exam, the total score, and the subjective questions such as multiple-choice questions and fill-in-the-blank questions. In this way, we can allocate the examination time reasonably in the exam, and we must avoid wasting a lot of time in unworthy places and affecting the answers to other questions. Take Anhui Mathematics College Entrance Examination as an example. The full score of Anhui Mathematics College Entrance Examination is 150, and the time is 2 hours, in which multiple-choice question 12, with 5 points for each question and * * * 60 points; Fill in the blanks with 4 questions, with 4 points for each question, *** 16, and 74 points for solving the first question. Therefore, after understanding these contents, we must arrange the problem-solving time reasonably according to our own situation. Generally speaking, the multiple-choice fill-in-the-blank questions should not exceed 40 minutes at the latest. According to our New Oriental training standards, students should complete the selection of fill-in-the-blank questions efficiently within 30 minutes. You must set aside more than an hour or more to deal with the big questions later, because big questions mean that you should not only think, but also write. Second, ensure the correct rate, learn to choose, dare to give up the exam, and must choose according to your own situation. The purpose of doing this is to ensure that you can get points for the topics you can do, get as many points as possible for some topics you can or can't do, and spend as little time as possible or even don't think about it at all. For students with good academic qualifications, if they feel that the choice of the previous fill-in-the-blank questions is relatively smooth and there is plenty of time, they can play the last finale and get high marks when the previous big questions are relatively stable. For ordinary students, the first thing to ensure is that most of the scores of the previous fill-in-the-blank multiple-choice questions will be relatively stable or even perfect. For the first few questions of big topics, spend as much time as possible and don't lose points on the topics you can do. The last two questions of the big topic, do a few if you can. Even if you don't do the next few questions, you should ensure the previous score, because the cost performance of the last two questions is far less than that of the previous ones. For students with poor level, first of all, we must do what we can to fill in the blanks. You can write a few questions if you have a big topic. But if it is too difficult to finish the last two finale questions, I suggest giving up boldly and not feeling bad, because even if you spend a long time doing and thinking, you may not get more points. If you spend this time filling in the blanks, you may get more benefits. In this regard, we don't have to blindly imitate others' practices. Again, we should consider it according to our own situation. There are often many students who have no exam skills and want to do all the questions well, but all the questions are completed in a hurry and full of loopholes. The questions that could have been done were lost because they were in a hurry or taken lightly, while some big questions behind them were only found to get 1 point and 2 points even if they were written on the paper. Such students just failed in the examination method, and we should learn such a lesson. Third, fast and accurate, there are multiple-choice questions, fill-in-the-blank questions and answer questions by hook or by crook in the exam. The essential difference between choosing fill-in-the-blank questions and solving problems is that you don't need to write the steps of solving problems. In fact, the proposer has hinted to us that it is allowed to choose fill-in-the-blank questions as long as you work out the answer, no matter what method you use. Many people who fail in the exam often make mistakes and taboos, that is, treat each question as a step-by-step solution. In this way, even if you can answer the question correctly, you waste a lot of unnecessary time. In fact, many people choose to fill in the blanks and carefully observe the numbers and options in the questions, which can eliminate some options, completely reduce the difficulty and even directly choose the correct answer. Many fill-in-the-blank questions often have many flexible skills, but because these skills are often not suitable for writing in papers, they are often ignored by us. For example, the clever methods commonly used in choosing fill-in-the-blank questions are: exclusion, combination of numbers and shapes, drawing observation, substitution verification and so on. These skills and methods are also instilled and infiltrated into students in the explanation of ordinary topics, and we will gradually cultivate students' consciousness in teaching. Everyone must pay attention to the choice of fill-in-the-blank questions, not only because of the score, but also because it will directly affect the mood of candidates in the exam, which often becomes the key to the success or failure of an exam. In short, we must study or ponder the methods and skills of the exam according to our own actual situation, and make a calm and correct choice in the exam in order to succeed in the exam. Finally, I wish you all good results in the exam.
