1, simplification of complex problems
There are generally two small items in the final exam of college entrance examination mathematics, and they are often very complicated. Candidates can decompose very complicated problems into a series of simple problems and solve them slowly. The college entrance examination is graded step by step, so candidates should calculate first. Even if they can't draw a conclusion, they can still get some points if they step on the score line.
Step 2 give up appropriately
For candidates with a good foundation in mathematics, the last question of the mathematical finale can generally get about half the score. However, because the last question is difficult and takes a long time, I suggest you get as many points as possible without wasting the overall examination time. If it can't be solved, we must learn to give up appropriately.

3. Reverse thinking
The last math problem in the college entrance examination is very difficult to solve, so reverse thinking is a very important problem-solving skill. If the examinee's thinking is blocked when doing the last math problem, he can try to explore new ways to solve the problem by using the method of reverse thinking, and often there will be breakthrough progress.

4. Dare to try
For candidates, when doing the last math problem, they should dare to try and think. If there are two questions in the finale, the argument of the second question will often use the conclusion of the first question. Therefore, if the first question of the finale is not proved, the conclusion can be directly applied to the second question.
