Xiaoao refers to Xiaoao class, which is a six-year compulsory school where junior high school and senior high school coexist. Every year, the top students choose the small Austrian class first, and the admission rate is high. The Olympic Mathematics Big Class is also a six-year compulsory school. However, there are also some students whose grades are not enough to enter the big class of Olympic Mathematics who are assigned to the small class of Olympic Mathematics.

In academic performance, students in the big Olympic class perform better than those in the small Olympic class. The "2+4" mathematics curriculum training mode is adopted in the Grand Olympic Class, that is, two years in junior high school and four years in senior high school, aiming at cultivating mathematics enthusiasts and improving mathematics quality. And 3+ 1 is the selection mode of the new college entrance examination. Mathematics, Chinese and foreign languages are compulsory subjects, while physics and history are optional.

Generally speaking, Xiao 'ao, Da 'ao and 3+ 1 have their own advantages. What kind of school to choose depends on your academic needs and interests.
