1. Understanding concepts: Make sure you have a full understanding of related concepts before you start to cover the issues. If you don't understand the terms, definitions or background information in the question, it is difficult to answer the question correctly.
2. View options: View options before reading the question can help you understand the topic and scope of the question and provide some clues when choosing the answer. Sometimes there will be interference items unrelated to the topic in the options, which need to be carefully identified.
3. Exclude the wrong options: Exclude the obvious wrong options, which can improve the accuracy of the guess. If one or two wrong options can be excluded, the success rate of guessing from the remaining options will be higher.
Mathematical problem-solving skills:
1, look across the street. When one of the options is positive X and the other is negative X, choose between them. There is only one correct answer. If there are two completely opposite meanings in the option, the correct answer is probably somewhere in between.
2. Extreme value method: In seeking extreme value, value and analytic geometry, the extreme situation is found for analysis.
Conventional method: the first question in mathematics will not be a, and the last question will not be a.
3. The answer is simple. The problem looks simple in numbers, the answer is complicated, and the problem looks complicated in mathematics.
4. Generally, the option with the root sign is not selected, and the option with 1 is generally selected. Graphic problem, select a special value.
Try to guess even if you don't know the answer in the exam, because the correct rate sometimes depends not on how much you know, but on the number of times you try and the accuracy of your guess.
