I'll be in Seoul for about 6 weeks this summer; one of my main goals while there is to study Korean. To that end, I'm thinking about enrolling in a 학원. Unlike a university, most of the 학원s offer month long courses every month. This is more convenient for me than the longer courses offered only once over the summer by the major universities.
The places I am considering are
1. Ganada

2. Seoul Korean Academy

3. Language Teaching Research Center

Does anyone have any experience with any of these, or know of any other options for Korean study in Seoul that are perhaps worth considering?
