How do you commute to work (or school)?

I live in Dogok, Gangnam, and my school is Sejong University located in Gwangjin near Konkuk University. I usually go to school by bus and subway. First, I ride the bus from my home to Hakdong station. Next, I transfer to the subway from Hakdong station to Children’s Grand Park station. Whether I’m late or not depends on how fast the bus arrives. Once I get to Hakdong station, I can finally arrive at my school within the next 15 minutes.
