Winning the lottery is good for both of us.

Mathematical modeling is more technical. The threshold for participation is relatively high. It takes a long time to accumulate pre-mathematics and applied programming techniques, so it depends on the team.

The challenge cup is divided into two parts: big jump and small jump. Jump: The extracurricular academic scientific and technological works competition, which I think has the highest gold content, is academic and is known as the Olympic Games of universities.

Jump: business plan competition. This is to form a team and write a business plan. To put it bluntly, it means writing. We need several students majoring in industrial management, especially accounting and marketing. This game feels a bit ridiculous. Most of them are just plans, and even the national gold medal may not be implemented. Any student can participate in this activity.

But generally speaking, the level of the Challenge Cup is higher, which is jointly organized by the Central Committee of the Communist Youth League, the Ministry of Education, the China Federation of Students and the China Association for Science and Technology.
