During every summer and winter break for students in Korea, academies of all types like to offer intensive classes. These classes are a way for the students to get ahead, catch up, or even to try out different academies without a long term commitment. As a foreigner, I sympathize for these kids since they are in academies literally all day everyday after school. Going to these academies double time during their vacation is probably the last thing they would ever want. However, as a teacher in Korea who is post-grad trying to pay back loans, this is a great way for me to earn some extra cash for the month.
