Shenyang Mathematics is subject to Beijing Normal University Edition, and the contents of grades 7, 8 and 9 are 3: 3: 4.
The proportion of easy questions, medium questions and difficult questions is about 5: 3: 2.
If the foundation of mathematics is not very good, it is suggested to consolidate the courses in grades one and two. We can divide the summer vacation, review the first and second days in the first half of the year, and try to teach ourselves the third part in the second half.
