1. Rolling rule:
If three or more options in the question are the same, then this option is probably the correct answer.
2. Extreme rule:
For function or algebra problems, if the range of values is given, we can find the maximum or minimum value of the function or algebra formula by derivation or collocation, so as to get the correct answer.
3. The law of cancellation:
Sometimes, some formulas that are difficult to calculate can be simplified by canceling, so as to get the correct answer.
4. Multiplication rules:
For ladder function or compound function, we can use the multiplication rule to calculate, so as to get the correct answer faster.
5. Multi-solution rule:
Some questions may have multiple correct answers. At this time, it is necessary to determine which answer is more in line with the meaning of the question according to the specific requirements of the question.
Generally speaking, there are many tips for the senior high school entrance examination, but the key is to master the basic knowledge and problem-solving ideas, which can not only improve the efficiency of doing problems, but also complete them more accurately.

In addition, the review of high school mathematics should pay attention to practice, do more problems, sum up mistakes and shortcomings in time, and find ways and ideas to solve problems. At the same time, we should also pay attention to the flexible application of mathematical knowledge, not limited to rote memorization, but through flexible combination and application to solve problems.
On the day of the exam, we should keep calm, carefully examine the questions, pay attention to the difficulty and score of the questions, and formulate reasonable problem-solving strategies. In the process of solving problems, pay attention to the steps of examining questions, drawing, formulating and calculating, and strictly follow the steps, so as not to be careless.
Finally, we should pay attention to the control of time, arrange the time reasonably according to the score and difficulty, ensure that each problem has enough time and energy to solve, and don't miss the score because of lack of time. Based on the above examination skills and methods, I believe that students will certainly achieve excellent results in the mathematics examination of the senior high school entrance examination.
