I came here this March and have still taking a Early-bird class for 10 month.
I've got known this center by my father and he strongly recommended here so I also did to my older sister who've already finished a Sparta class. She's really happy with that and got big motivation. That makes her to go to abroad to have world wide experience.
For me, to prepare a certification of something , I've got come here to learn English.
At the beginning of the class, I felt a bit strange the way to learn English but followed it continously.
It really works. Specially, review is very important. This way is only the way to speak English in Coach Park center. I guess anybody can follow and learn English easily and interestingly. A remarkable acheivement is that I can speak in English very naturally and use native expressions cause we learn English by Drama and News topic.
Whenever come here, I can see many of people who have passion and ambitious. I can't explain how much energy is. That makes me to move and to have passion. 
I like this way to learn English and hope to do here forever!
I'm very glad to meet this center so strongly recommend here as well. Thanks!
