Amc competition is useful in China. First of all, the AMC competition is sponsored by the American Mathematical Association, and its achievements have always been relied on by official and non-governmental organizations in the United States and North America. Therefore, participating in AMC can enhance students' international competition experience, enhance students' international study and competition background, and improve their admission competitiveness. Secondly, AMC scores become the basis for evaluating applicants' academic performance in mathematics. For students who want to apply for prestigious universities in the United States and Canada, the winning experience of AMC competition is an important stepping stone. In addition, AMC competition can fill the vacancy of China students' Olympiad competition, and it is also an important plus item for students who want to transfer to international schools.
