Mathematics answering skills in college entrance examination
1, multiple choice questions
Pay attention to the examination questions. Read the topic several times to find out what this topic seeks, what it knows, and what is the relationship between seeking and knowing. Speak clearly before you begin to answer.
The order of answering questions is not necessarily according to the question number. You can answer the questions you are familiar with first, start with the questions you are sure of, let yourself enter the problem-solving state as soon as possible, and generate the passion and desire to solve problems, and then answer the unfamiliar or unfamiliar questions. If you have time, try to spell out those questions that you are not sure or can't start. This may be able to play beyond the level.
About 70% of multiple-choice questions in mathematics are direct methods, so we should pay attention to the understanding and application of symbols, concepts, formulas, theorems and properties, such as the properties of functions and sequences.
Mining implicit conditions, pay attention to error-prone and confusing points, such as empty sets in sets, definition domains of functions, restrictive conditions of application problems, etc.
Control time. Generally speaking, it should not take more than 40 minutes, and the multiple-choice questions should be completed in about 25 minutes. Try to answer quickly and accurately, and leave enough time for the following answers to prevent "losing points over time".
Step 2 fill in the blanks
Problem-solving strategies: Because there are similarities between fill-in-the-blank questions and multiple-choice questions, some problem-solving strategies can be used. I won't say it here, but I'll give you some suggestions according to different characteristics:
Fill-in-the-blank questions are mostly computational (especially inferential) and conceptual (or qualitative) questions, and the answers must be calculated or logically inferred according to rules; The result of the answer must be accurate in numerical value and standardized in form, such as the representation of set form and the completeness of function expression. If there is something wrong with the result, it is zero.
The answer to the fill-in-the-blank question in the exam instructions is "correct, reasonable and fast". Therefore, the basic strategies for answering are: operate quickly and avoid making a mountain out of a molehill; Stability-deformation should be stable to prevent impact; Complete-the answer should be complete, avoiding being right and incomplete; Live-live to solve problems, don't copy them mechanically; Careful-careful examination of the questions, not sloppy.
Step 3 answer questions
For the same topic, some people have a deep understanding, while others have a shallow understanding; Some people solve more, while others solve less. In order to distinguish this situation, the college entrance examination scoring method is to give as many points as you know.
For the vast majority of candidates, it is more important to score from the questions that cannot be taken down. We say that what kind of problem-solving strategy there is, what kind of scoring strategy there is. Writing down the real process of your problem solving is the whole secret of "grading by stages"
