Hello. I graduated from Seoul National University and am currently the director and instructor of a math academy specializing in elementary, middle, and high school math. While teaching high school students, I always feel that it is truly difficult to correct the habits of students who have struggled with math since elementary school. Only when elementary math habits are properly established can students become strong in high school math. This naturally led me to believe that I should pay even more attention to the math education of elementary students. Therefore, through Kookgeu, I aim to help many students come to like and excel at math.
