Best english class

I would like to say thank you to teacher Sarah. At first, I was worried about my speaking skills. and also curious if okay to practice English and Korean at the same time in the class. But Sarah did it for me. She helps me a lot not only English but Korean speaking especially in a presentation. After continuous praticing and listening, I have improved a lot. Lessons were very relaxing and we talked about everything. She is a very patient teacher who always encouraged me a lot!
