1. Learn programming languages: Master at least one programming language, such as C++, Java or Python. Understand basic grammar and data structure, and be able to write simple programs.

2. Familiar with algorithms and data structures: Learn common algorithms and data structures, such as sorting algorithms, graph algorithms and trees. Understand their principles and application scenarios and be able to use them flexibly.

3. Brush exercises: brush questions to improve programming ability and problem-solving ability. You can choose some online programming platforms, such as LeetCode and Codeforces, to practice and participate in competitions.

4. Attend training courses or courses: You can sign up for some training courses or courses of Informatics Olympiad for systematic study and training. These training courses usually provide some classic topics and problem-solving skills.

5. Team entry: If there is an opportunity, you can join the team. Teamwork can improve the efficiency and quality of problem solving, and at the same time, we can learn from each other and communicate with each other.

6. Do more simulation games: Participating in some simulation games can improve your competition experience and ability to cope with stress. Mock matches can help you get familiar with the rules and problems of the game and find out your own shortcomings.

7. Read more relevant books and materials: read some books and materials related to informatics olympiad, and learn some classic algorithms and problem-solving ideas. This will broaden your knowledge and improve your ability to solve problems.

8. Keep practicing and summarizing: It takes long-term persistence and hard work to participate in the Informatics Olympics. Keep a certain amount of practice time every day, constantly sum up and reflect on your own problem-solving process and methods, and constantly improve your level.
