1, the number of participants is small: the number of participants in Xiamen public schools is small. Compared with schools in other cities, the fewer participants, the less chances of winning prizes.
2. The quality of teaching is not high: The quality of mathematics teaching in public schools in Xiamen may not be as good as that in other cities, which leads to students' relatively weak mathematical literacy and problem-solving ability, and it is difficult to achieve good results in the Excellence Cup mathematics competition.
3. Lack of training and guidance: Public schools in Xiamen may lack professional training and guidance for mathematics competitions and cannot provide better preparation and support for students. It should be pointed out that the above factors are only the reasons that may affect Xiamen public schools to win the prize in the Excellence Cup Mathematics Competition, and the specific situation needs to be analyzed according to the actual situation.
