1. Learn the basics: Mathematical modeling competition needs some knowledge of mathematics and computers, so you need to master some basic mathematical knowledge, such as linear algebra, probability theory and calculus. At the same time, you need to be familiar with some programming languages, such as Python, R and so on.

2. Learn modeling skills: Mathematical modeling is not only to solve problems, but also a way of thinking. You need to learn how to abstract practical problems into mathematical models, how to solve models by mathematical methods, and how to interpret and analyze results.

3. Participate in the simulation contest: By participating in the simulation contest, you can understand the process and rules of the contest and improve your ability to take the exam. At the same time, you can also test your knowledge and skills through competitions.

4. Read relevant books and papers: By reading relevant books and papers, you can learn the latest research results and methods and improve your innovation ability.

5. Teamwork: Mathematical modeling competitions usually require teamwork, so you need to learn to cooperate with others, work together and accomplish tasks together.

6. Do a good job in time management: Mathematical modeling competitions are usually limited in time, so you need to learn how to arrange your time reasonably to ensure that you can complete the task within a limited time.

7. Stay calm and focused: You may encounter some difficulties and challenges in the competition, so you need to stay calm and focused, and don't be defeated by difficulties.
