I couldn't even speak and write English well before, but I have reading and interpretation skills the ability to read and interpret English sentences. I think I can interpret English better than usual. This is because I have more opportunities to approach English through classes. And even if I don't understand words, I've developed the ability to predict what they mean and read sentences. 

Not only reading, but I also improved my English writing skills. At the beginning of class it was awkward to make sentences using English. However, there were many opportunities to write essays through classes. I couldn't use a good essay from the beginning. Nevertheless, I was able to write improved essays with feedback from my professor every week.

In addition, I also improved in discussing with classmates. Before taking this class, I had few opportunities to discuss one topic with people, so I didn't like discussing. However, my speaking ability whether in English or Korean improved through weekly discussions. And I became the leader of the team and led the direction of the discussion directly.

Finally, I think my speaking skills have improved. That's not to the extent that I speak sentences perfectly without being blocked. But I got used to communicating in English more than before I took classes. Thanks to the professor's understanding of what I said, communication has improved. I don't think I'm afraid of taking class in English anymore. It can be said that this has improved in itself.
