A problem-based textbook that makes middle school math easier

Concept organization and type classification faithfully reflecting the 2015 revised curriculum
Configure all problems except difficult ones
Presented by subdividing the types
Optimal descriptive subjective questions based on the increased proportion of descriptive questions

1.
The optimal problem-solving textbook to reduce learning burden
It is structured to cover the essential concepts for each topic in detail and to allow sufficient practice of basic types.
By boldly omitting difficult content, questions that are rarely tested, or questions that do not fit recent test trends, we have reduced the learning burden and improved the learning achievement of students who struggle with math.

2.
Type segmentation
After covering all the easy school exam questions, we've broken them down into more specific types based on the concepts and solution methods needed to solve them, so you can learn problem-solving strategies for each type.

3.
three-dimensional learning
The difficulty of the problems is divided into two levels, A and B. By strengthening the basic problems of level A and further dividing the types of level B, three-dimensional learning is possible by level of difficulty and type.

4.
Type practical finishing
We have organized the final learning problems for each type of Stage B to help you develop problem-solving skills for each type and prepare you perfectly for real-world situations.
