Math skill code of college entrance examination 1. If the answer has a radical symbol, don't choose it.
2. If the answer is 1, please select.
3. When all three answers are yes, choose the right one.
4. When one is positive X and the other is negative X, choose one of them.
I recommend: 20 17 national college entrance examination, volume 2, liberal arts mathematics answer template.
5. If the question looks simple in numbers, then choose complex mathematical answers, and vice versa.
6. If you choose the previous question and this question, it is not suitable to do this article if three identical ones appear in succession.
7. Whether you answer math well depends on your eyes.
8. when none of the above is practical, choose B.
Mathematical function method is to convert some calculations into functions, first bring in the answers, then move the terms to turn one side of the equation into zero, and then you can roughly draw the expression of the function to see if there is a unique focus with the zero point, so that you can roughly judge the answers or find the answers closest to the zero point!
Mathematical empirical method: also used for mathematical sorting or conventional problems. First, for example, find the triangle area. Look at the answers A: 12, B: 13, C: 6, D: 1 1. First, 12, 13, 1 1 are obviously the wrong answers. Secondly, there must be a trap of forgetting to divide the triangle area by 2, so the correct rate of C's answer is high.
Substitution method, this series of methods are often given some conditions, such as a greater than or equal to 0, less than or equal to 1. B is greater than or equal to 1 and less than or equal to 2. Considering some special circumstances, it may be complicated for you to find some formulas for combining ab. But if it is a multiple-choice question, you can try a=0.5 and b= 1.5. There is also a formula that can bring the answers in the options to the questions for calculation.
How to review the basic knowledge of mathematics, the analysis of the basic problem-solving ideas of mathematics and the application of mathematical methods are the most important things in the first round of review. Sort out knowledge points, form a complete knowledge system, and ensure a firm grasp of basic concepts and formulas. Down-to-earth, thoroughly understand every knowledge point, and make clear their requirements and connections with other knowledge.
The review course is large in capacity, rich in content and short in time. In order to improve the review efficiency, we must synchronize our thoughts with the teachers'. Preview is an important way to achieve this goal, and it is necessary to do "two before two", that is, preview before attending classes, review before doing homework. In order to improve the initiative of attending classes and reduce the blindness of attending classes.
After previewing and listening to the teacher, you will choose what the teacher said in your memory and focus on what you don't have, thus improving the review efficiency. Preview can also cultivate your self-study ability.
