Revealing the secret of the "magic skill" of the mathematics answer question of the college upgrade: the question is good!
Have you ever felt scrambled in a math exam room because of the tight schedule and the difficulty of the questions? Or do you feel clueless about certain types of questions and have no choice but to give up? Don't worry, today I will reveal to you a mysterious math answering technique - Mengjie**! Let you in the mathematics test of the first college upgrade, even if you encounter problems, you can calmly deal with them, and easily get points!
1. The past and present life of Mengjie**
First of all, let's make it clear that the answer is not based on groundless guessing, but based on certain mathematical knowledge and problem-solving experience, and through reasonable speculation and judgment. This technique can often play an unexpected effect in the examination room, helping students solve more problems in a limited time.
The origin of Meng's question is impossible to verify, but it is widely spread in the rivers and lakes of mathematics exams. Some say it is the crystallization of the wisdom of ancient scholars, and some say it is a lifesaver for modern candidates. In any case, if you master the problem**, you will have a key to open the treasure house of mathematics!
Second, the basic principles of the question
Know yourself and know your opponent, and you will not be defeated in a hundred battlesIn the examination room, if you want to succeed in the question, you must first have a clear understanding of your own mathematical knowledge system. Be clear about the types of questions you are good at and your weak points, so that you can be targeted when covering questions.
Observe the stem and capture the information: Read the stem carefully to capture key information. Sometimes, a word or two or a number in a stem can give you an idea of how to solve a problem.
Use the elimination method to narrow down the scope: For multiple-choice questions, if you can't get a direct answer, you can try using the elimination method. By eliminating the obviously wrong options, you can narrow down the answers and improve the accuracy of the questions.
Use your instincts to make a decisive move: Sometimes, intuition can also be a treasure of the question. When you have a strong premonition about an answer, don't hesitate to make a decisive move! Of course, intuition doesn't come out of nowhere, it's often based on your subconscious mind and past problem-solving experiences.
Third, the practical application of the Mongolian question
Multiple-choice masking skills
Option distribution method: Observe the distribution of options, if an option appears less often, then it is likely to be the correct answer. Because the questioner will often increase the difficulty of the question by setting distractions.
Option comparison method: Compare the differences between the options and find the contradictions. Often, the option where the contradiction lies is more likely to be the correct answer.
Option substitution method: Validate the options by substituting them into the stem. If substitution stems are logical, then this option is likely to be the correct answer.
Fill-in-the-blank masking skills
Special Value Method: For some abstract fill-in-the-blank questions, you can try to solve them by substituting special values. For example, constants such as -1 are a common choice for special value methods.
Unit method: Speculate on the answer using the principle of unit conversion or unit consistency. For example, when solving for areas or volumes, pay attention to the conversion and consistency of units.
Number Sequence: For fill-in-the-blank questions involving sequences, you can try to find out the rules or general formulas of the sequences to guess the answers.
Answering questions
Step-by-step scoring method: For complex questions, try to break them down into a few simple steps. Even if the final answer is wrong, you can get partial points as long as the steps are reasonable.
Result inversion method: Starting from the results given by the question, the process of solving the problem is deduced backwards. This method is especially effective in proof questions.
Graphic combination method: Use graphs to assist in problem solving. For example, in a geometry problem, drawing an accurate figure can help you better understand the meaning of the problem and find the solution to the problem.
Fourth, the precautions for the question**
Don't abuse it: Although the questions are magical, they are not in the examination room, and they should still be based on solid knowledge and problem-solving ability, and the questions can only be used as an auxiliary means.
Time management, reasonable allocation: When using masked questions**, be sure to pay attention to time management. Don't spend so much time on one question that you can't complete the others.
Stay calm and have a calm mind: When faced with a difficult problem in the exam room, it is important to stay calm and have a calm mind. Don't let the gain or loss of one question affect the mood and performance of the whole exam.
V. Conclusion
In short, as a mysterious mathematical answering skill, although it can help students solve problems to a certain extent, it is ultimately inseparable from a solid knowledge base and problem-solving ability. Therefore, in the process of preparing for the exam, everyone should still focus on learning and strive to improve their mathematical literacy and problem-solving ability. Only in this way can you achieve excellent results in the mathematics exam of the ** college upgrade!
