There are four multiple-choice questions in the new college entrance examination mathematics, and the scoring standard is 5 points for each question, 5 points for all, 2 points for some, and 0 point for wrong or not. Each multiple-choice question has four options, and the correct answer is often 2 or 3.

Mathematics multiple-choice answering skills should be "better than lacking" without fully mastering the multiple-choice options. Only by correctly selecting all the correct options of a multiple-choice question can you get the full score (5 points) of this multiple-choice question. And if there are multiple correct options, even if only one correct option is selected, you can get 2 points. However, if you choose the wrong option, even if there is only one wrong option, you can only get 0 points.

In this case, unless you are absolutely sure, you'd better only choose the option you are most sure of, so as not to cause the regret that the wrong option is not divided. If you are really not sure, choose an option that you think is most likely to be correct. Because doing so can not only ensure as many as possible to get 2 points, but also avoid the situation of not getting points because of multiple choices and wrong choices.

Choose at most 4 and at least 2 of the correct options in each multiple-choice question. It is easy to understand that the option of "choose at most 4" is correct. Because each multiple-choice question has four options, since it is a multiple-choice question, the number of correct options can only be four pairs at most.

Mathematical problem-solving skills of multiple-choice questions in college entrance examination 1. Special value test method: for general mathematical problems, specialization can be carried out in the process of solving problems, and the principle that the problem does not hold in special circumstances and does not hold in general circumstances can be used to achieve the purpose of removing the false and retaining the true.

2. 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 once extreme value analysis is adopted.

3. Exclusion method: using the known conditions and the information provided by the selection branch, 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.

4. 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.

5. Recursive induction: a method of reasoning through topic conditions, looking for rules, and thus summing up the correct answer.

6. Forward deduction method: a method of using mathematical theorems, formulas, rules, definitions and meanings to obtain results through direct calculus and reasoning.

7. Reverse verification method: substitute the selected branch into the trunk for verification, so as to deny the wrong branch and get the method of correctly selecting the branch.
