The 1 level of 2+4 academic system has reached the general level of science classes, and the teaching materials should be expanded and extended.

Beijing Eleventh School 2+4 is a six-year system, with two junior high schools and four senior high schools. You don't need a senior high school entrance examination, just a college entrance examination. Because I finished the junior high school content in two years, the textbooks of all subjects are basically compiled by the teachers of the eleventh school, which is self-contained.

Eleven, two plus four mathematics from easy to difficult, divided into number IIIA (give), number four, number five.
