How to get the correct rate of multiple choice questions in mathematics 1? Getting questions is also a science. I am a senior three student, and the success rate of getting math questions 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.
Substitution method of multiple choice questions in college entrance examination mathematics
This series of methods often give some conditions, such as a greater than or equal to 0 and 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. Backward method!
Interval method
This method, also called exclusion method, relies on roughly calculated data or guesses some data when answering multiple-choice questions in college entrance examination mathematics. For example, how many angles are given to a topic, 30 and 90. Obviously, the answer must be 90 30 degrees, 120 plus or minus 30 degrees. Or some answers related to 30, 60 or 90 degrees.
Coordinate method
If you can't find a way of thinking in some math graphics problems in the college entrance examination, you can use the proportional method first, and then use the coordinate method. You can directly find the coordinates of two points, without considering any trigonometric function, and directly bring in the formula of angle (cos formula), vertical line, length and tangent separation of high school functions. Go straight to Huanglong, you don't have to find a point of view to do anything troublesome.
ratio method
Proportional method is a simple rogue method for multiple-choice questions in mathematics in college entrance examination. If you encounter graphics problems, mark the known first, measure the unknown with a protractor, and then it is time to witness the miracle! ! ! The ruler measures the proportional relationship between two solid lines, and then the length of that side can be obtained by approximately estimating the ratio through the known edge.
