First, an overview of the exam situation.
For many candidates, the quantitative relationship seems to be an insurmountable hurdle. In Zhejiang province, there are many problems and the most difficult ones. Therefore, many candidates will do it at the end of the exam, and the more they do it, the more nervous they become. In fact, the quantitative relationship is not as difficult as imagined. As long as everyone can prepare for the exam scientifically and reasonably, this module is still easy to get points.
In recent years, the number of questions fluctuates every year, with 5 or 10 questions and 15 or 20 questions. The total number of questions in the number push+operation is mostly 25 questions, and occasionally there are 20 questions. After 202 1 year, three kinds of ABC test papers appeared, of which Volume A (comprehensive class) calculated 5 questions and calculated 20 questions; Volume B (basic class) is exactly the same as Volume A in the deduction and operation of numbers. Volume C (law enforcement) tests 5 questions by number, and tests 15 questions by operation. Compared with AB paper, there are five questions missing, and everything else is the same.
If you save the exam, the suggested length of each question is one minute, which can be adjusted according to the difficulty, but overall, there is one question per minute on average.
Second, the test data
Third, sort out the test sites
Through the study of quantitative relations in Zhejiang Province in recent seven years, it is found that multilevel series and recursive series are the most frequently investigated in numerical reasoning. The most frequently tested mathematical operations are equation problems, permutation and combination and probability, travel problems, economic problems and geometric problems, which are basically more than one every year. In addition, the maximum problem and basic calculation are also the "darlings" of provincial examiners. Although the provincial examination involves many knowledge points and few repeated test sites, more than 70% of the questions are high-frequency test sites. Therefore, candidates should strengthen the consolidation of high-frequency test sites in the process of preparing for the exam, so that they can find that the real questions are familiar and have many similarities with the old questions, which greatly improves the speed of extracting knowledge points and solving problems.
Fourth, the examination trend
Through the study of real questions in recent seven years, it is found that the questions are flexible, close to the reality of life, and pay more attention to solving ideas and skills. In the 2022 Zhejiang Provincial Examination, some questions are no longer a single knowledge point, but a mixture of knowledge points, paying more attention to examining the basic skills of mathematics. In particular, there are more and more maximum questions with various combinations of questions. This kind of questions are often long, and candidates sometimes can't find out the knowledge points they have examined immediately, so they choose to give up.
However, the difficulty of this kind of topic is not necessarily great, and it may involve the experience in life to extract the key information in the topic, then find the knowledge points to be examined, and then match the corresponding problem-solving skills to get the answer. In the actual examination, due to the time limit, we often can't solve problems by conventional methods, but need some skillful methods, such as substitution and exclusion, crossover, numerical characteristics, assignment and so on. , can save a lot of answering time, which requires us to master and use these methods flexibly.
Suggestions on learning verbs (abbreviation of verb)
The quantitative relation module requires candidates' mathematical foundation and logical thinking ability, so its preparation for the exam is a step-by-step process. We can neither ignore the enemy nor be eager for quick success. Instead, we should first lay a good foundation, master the characteristics of various questions and solve problems, and then gradually improve on this basis.
(1) Mathematical foundation is the most important. A solid mathematical foundation is the guarantee of steady improvement in the later period. If you don't learn the basic knowledge well, any skills and methods are useless. Therefore, when reviewing this module, we should first master the basic mathematics knowledge skillfully. For example, solving equations and equations, calculating the perimeter, area and volume of geometric figures, calculating the greatest common divisor and the least common multiple, summing arithmetic progression and geometric series, and understanding odd, even, prime and composite numbers.
(2) Grasping the characteristics and methods of common problems is the core. There are only a few types of quantitative relationship problems in Zhejiang Province, such as engineering problems, travel problems, geometric problems, maximum problems, permutation and combination, probability and so on. Everyone should know the characteristics of each question type. For example, for engineering problems, you should know what kind of problems are engineering problems, how many different types of engineering problems there are, and how to solve each type of problems. In addition, there are some problems that can be solved directly by formulas. You should understand and remember these formulas so that you can use them easily.
(3) Skillful use of methods is the key to speed up. On the premise of laying a solid foundation, we can also try some ingenious methods to improve the speed of solving problems.
(4) The amount of questions is skillful and not blind. There are always some problems in each set. For this part of the so-called "low cost performance" problem, it is not recommended that you spend too much time on it. We need to make a reasonable choice. Of course, the amount of questions is not blind, but can have a certain degree of basis. We should have frequency problems according to four options. The frequency of a, b, c and d in a set of test questions should be roughly equal. At this time, you can observe which option appears less frequently, and all the problems that do not appear will be covered.
The above are all the answers to the quantitative analysis of the Zhejiang Provincial Examination. For more skills, please pay attention to the Gao Dun public examination.
