Samchun has created basic, intermediate, and advanced apps for Korean history.
I hope that this will help those who are preparing for the Korean SAT for the SAT.
It is judged that the degree of difficulty of Korean history is between intermediate and advanced.
So, Samchun is not the same as Samchun's middle-class Korean app, except for the explanatory notes.
If the Korean history textbook of high school in 2019 is sold, we will purchase it, study it, and organize the contents.

thank you.
