1. basics: first of all, you need to master some basic mathematical knowledge, including algebra, geometry, calculus, probability theory and statistics. This knowledge is the basis of solving mathematical modeling problems.

2. Learning modeling methods: Mathematical modeling is a process of abstracting practical problems, describing them with mathematical language, and then solving them with mathematical methods. You need to learn some common modeling methods, such as linear programming, nonlinear programming, dynamic programming, graph theory, queuing theory, decision theory and so on.

3. Learn programming skills: In the mathematical modeling contest, you may need to use computer software to assist your modeling and solving process. So you need to learn some programming languages, such as MATLAB and Python.

4. Do simulation questions: By doing some simulation questions, understand the questions and problem-solving ideas of mathematical modeling competition, and improve the problem-solving ability.

5. Team-building: Mathematical modeling competitions usually need to be conducted in groups of three people. You need to find some people with common interests and goals to form a team together.

6. Cultivate teamwork spirit: In a team, everyone has his own strengths and weaknesses. You need to learn to respect others, give full play to everyone's advantages and solve problems together.

7. Do a good job in time management: Mathematical modeling competitions are usually time-limited. You need to learn to arrange your time reasonably and ensure that all the work is completed within the specified time.

8. Keep a good attitude: You may encounter many difficulties and challenges in participating in the mathematical modeling competition. You need to keep a positive attitude, not afraid of failure, and be brave in challenges.
