How to cheat in the rematch of Jiangxi Division of Senior High School National Mathematics League? Ask experienced masters to teach geometric number theory and miscellaneous problems. What if I can't do it? Make the steps of proving the problem more complicated, and finally write down what needs to be proved, and you will get half the score.

Geometry problem is skill plus luck. Write everything down as much as you can. Finally, come to an emergency stop, sum up what you have written, write what you have seen, and you can cheat.

That's all. I'm going to take the exam soon.
