1, you should have a complete and comprehensive understanding of your own mathematics learning, and according to your own situation, the focus of the exam should be accurate to prevent "picking sesame seeds and throwing watermelons". Therefore, in your mind, you must give a deadline for the finale or several "difficulties". If you exceed the upper limit you set, you must stop. Go back and carefully check the previous questions, try to ensure that you have multiple-choice questions and fill-in-the-blank questions, and try to check the previous solutions.

2. It is a problem of solving the mathematical finale. The first question is not a problem for most students; If you can't understand the first question, don't give up the second question easily. The process will be written as much as possible, because the mathematical solution is graded step by step, and the writing must be standardized, the handwriting should be neat, and the layout should be reasonable; Write as much as possible in the process, but don't talk nonsense, and try to avoid unnecessary components in the calculation; Try to use more geometric knowledge, less algebraic calculation, try to use trigonometric functions, and less the properties of similar triangles in right triangles.

3. Solving the mathematical finale problem can be generally divided into three steps: carefully examining the problem, understanding the meaning of the problem, exploring the idea of solving the problem, and answering correctly. The examination of questions should comprehensively examine all the conditions and answering requirements of the questions, and grasp the characteristics and structure of the questions as a whole, so as to facilitate the selection of solving methods and the design of solving steps. To solve the mathematical finale, we should be good at summarizing the important mathematical ideas implied in the mathematical finale, such as the idea of reduction, the idea of combining numbers with shapes, the idea of classified discussion, the idea of equations and so on. Understand the relationship between conditions and conclusions, the relationship between geometric characteristics of figures and the number and structural characteristics of numbers and formulas, and determine the ideas and methods of solving problems. When thinking is blocked, we should adjust our thinking and methods in time, re-examine the meaning of the question, pay attention to excavating hidden conditions and internal relations, and prevent us from falling into a dead end and giving up easily.
