For non-mathematics majors, the national college students' mathematics competition is basically an advanced mathematics competition (only advanced mathematics is tested in the preliminaries, and some lines are tested in the finals). The difficulty of undergraduate advanced mathematics can be ranked from middle to upper, which can be said to be a very important and difficult basic course for engineering students.

Because the difficulty and overall level of the competition questions in each competition area are different every year, it is difficult to accurately match the scores with the award-winning level. Combined with the experience of participating in the competition, the author thinks that 30%-40% of the topics in the preliminaries can win prizes, and more than 60% of the topics are expected to win the first prize.
