A focused study guide consisting of problems similar to those in the Strong B level

1.
1:1 similar problems to the B stage of Sen, allowing for focused/repetitive learning of the type
2.
A type of textbook that is less burdensome to learn than a strong textbook

What if you only want to study level B of Sen?
What if the C level of Sen is too difficult?
I solved the strong problem, but what if I want to solve the type problem again?
Want to quickly check the type?

The correct answer is 'Strong B'.
Sen B consists of problems similar to the B level of Sen, so when used with Sen, repeated learning of the type is possible.
With Strong B, solidify the types you already know and improve your weaker ones, so you can master every type! Strong B for efficient and complete type learning!
