KGSP plan of study

I have had learning English since I was four. It's not difficult for me to understand English but it's still hard for me to speak in English clearly. And so for Korean, I have had learning it since 5 years ago. Same with English, it's also hard for me to speak in Korean clearly, but I can read, write, and understand it well. Although I couldn't take any English and Korean proficiency test yet, I can surely tell you that I'm in intermediate level on both English and Korean.

Since my problem is in speaking, before I go to Korea, I will try to speak in English and Korean, and I will record my voice when I do it. And because I like to write and since I must add my English and Korean vocabulary, I will write a 400 words fiction story in both English and Korean.

After I come to Korea, I will read English and Korean books, journals, etc as much as I can. I will also speak in English or Korean all the time. And then, I will pass TOPIK 3 or TOPIK 4 in my first try.
