Is There a Language School in Korea?

I think I started going to what would eventually be like my actual high school since second grade. The class that I was in, most of the people were one year older. And then me and this other guy, we were like the only people in that class who were like in our grades. So like high school class of 2014, pretty much. We started off with like a pretty big group when he was in second grade. Like I think it was probably like almost 30 people. And then by the time it went to like the graduating level class, it was like 20. But looking back, it's kind of impressive for someone or for like an immigrant community to be able to organize something
