It's awesome. If self-studying with a book feels like a bullet, this lecture feels like driving a tank to the test site. I was crying a week ago and finished the lecture in two days. Teacher, I passed with a score of 95!!!!!!!!!!!! It was worth reading this lecture twice with tears in my eyes for a week. Thank you so much. A true teacher. This lecture costs less than 100,000 won. Are you an angel...?
