1.
Provides a 1:1 similar problem to the B stage of Sen
〈Strong B Math〉 is a 1:1 similar problem structure of Strong B level problems, allowing for type-focused and repetitive learning.

2.
Reduced learning burden
For students who find Level C of the Strongest difficult, Level B is designed to be an intensive learning experience, reducing the learning burden compared to Strongest.

3.
Efficient self-directed learning and repetitive learning possible
We have provided a “Learning Implementation Plan” for each unit so that students can proactively plan and repeatedly learn about their weak areas.
