Hello,This is Il-Sun Jeong, the director.Based on my experience of planning and operating an English education program for employees at a large domestic corporation, I have been developing customized English classes for learners at high school sites for over 10 years. In addition, the high school entrance team has accumulated vast amounts of data while guiding numerous top-ranking students for entrance exams. Now, by pouring out the experience of the past 15 years, we want to approach our students with a systematic learning system that has never been seen before.
