There is a great difference between the mathematics contest proposition group and the college entrance examination mathematics proposition group. The topics of the competition generally focus on examining students' innovative thinking ability. For example, this problem seems to have no solution, but it can be solved by another way of thinking. However, the contents of the mathematical investigation in the college entrance examination are all within the requirements of the syllabus, and no matter how the topic is changed, it is all about this knowledge point, so many students with full marks in mathematics have traces to follow. They have mastered the knowledge points of the college entrance examination and understood the intention of the questioner. If they are not careless in calculation, it is really not difficult to get full marks. I hope it helps you!
