How to get 1 math multiple-choice questions 1? Getting questions is also a science. I am a senior three student, and my success rate is over 70. First of all, make it clear that the problem can't be pure, and you must have the effect of seeing the problem after reading it. If you can't do it after reading the multiple-choice questions, look at the options first, some can be excluded, and then analyze according to the conditions of the questions, and some options may be excluded, which will be much easier.
If you can't rule out any of them, then consider the option. If there is an answer about extracurricular (which rarely appears in class), it is probably that. If the number of options is 4, usually the second largest option is the correct option. Looking at the options alone, there are generally more BD and less A. One more thing, don't change it after you choose it unless you are more than 90% sure.
2. As far as I know, the first question in mathematics is generally not A; The last question will not be a; The answers to multiple-choice questions are evenly distributed; Fill in the blanks not only with 0 or1; If the answer has a root sign, don't choose; If the answer is 1, select; When all three answers are yes, choose the right one; When one is positive x and the other is negative x, choose one of them; The topic looks simple, so the answer is complicated, and vice versa; What to choose in the previous question, what to choose in this question, if there are three identical ones in succession, it is not; When none of the above is practical, choose B.
In the calculation, you should write an answer first. If the number of options is 4, usually the second largest option is the correct option. Looking at the options alone, there are generally more BD and less A. One more thing, don't change it after you choose it unless you are more than 90% sure. Fill in the blanks according to the selection of related graphics can take special values.
You can't make a big problem, you can't use the conclusions you ask, and you can't deduce the conclusions you can think of according to the conditions. Usually you have points. If you are lucky, you can get more than half of 1. Fill in the blanks carefully, jump without thinking for 2 minutes, don't write the most possible answer, the chance of getting it right is not small.
1 math multiple-choice questions answering skills 1. Exclusion method: using the information provided by known conditions and options, three wrong answers are excluded from the four options, so as to achieve the purpose of correct selection. This is a common method, especially when the answer is a fixed value or has a numerical range, special points can be used instead of verification to exclude it.
2. Extra special value test method: For general mathematical problems, the problem can be specialized in the process of solving problems, and the principle that the problem does not hold in special circumstances can be used to achieve the purpose of removing the false and retaining the true.
3. Extreme principle: analyze the problem to be studied to an extreme state, so that the causal relationship becomes more obvious, thus achieving the purpose of solving the problem quickly. Extreme value is mainly used to find extreme value, range and analytic geometry. Many problems with complicated calculation steps and large amount of calculation can be solved instantly through extreme value analysis.
4. Forward deduction method: A method that uses mathematical theorems, formulas, rules, definitions and meanings to get results through direct calculus and reasoning.
5. Reverse verification method (the verification method of substituting the answer into the stem of the question): a method of substituting the option into the stem of the question for verification, thereby denying the wrong option and getting the correct answer.
6. When it is difficult to solve the problem from the front, you can gradually find a qualified conclusion from the options, or draw a conclusion from the opposite side.
I recommend: the most comprehensive math multiple-choice skills in the college entrance examination.
7. Number-shape combination method: a method of making a figure or image that conforms to the meaning of the question according to the conditions of the question, and obtaining the answer through simple reasoning or calculation with the help of the intuition of the figure or image. The advantage of the combination of numbers and shapes is intuitive, and you can even measure the result directly with a square.
8. Recursive induction: a method of reasoning through topic conditions, looking for rules, and thus summing up the correct answer.
9. Characteristic analysis method: analyze the characteristics of questions and options, find out the rules, and summarize the methods of correct judgment.
10. Valuation selection method: For some problems, due to the limitation of subject conditions, it is impossible (or unnecessary) to make accurate calculation and judgment. At this time, we can only get the correct judgment method from the surface by means of estimation, observation, analysis, comparison and calculation.
