After years of educational research and practice, Yi Jiaer's mathematics team has gathered the elites in the education field, and summed up a set of effective brand-new educational models in view of the common phenomena in students' mathematics learning, such as "good but not good", "knowing but not learning" and "being tired of learning". On the basis of ensuring students' interest in learning, it can improve students' grades, stimulate students' thinking and teach them problem-solving skills. In order to implement the educational concept of "teaching students in accordance with their aptitude" and enhance the brand competitiveness of Yi Jiaer Mathematics, in the spring of 20 10, Yi Jiaer Mathematics specially set up two classes: advanced class and elite class to meet the needs of students at different levels.
