How I study English

I like speaking English, but I can't speak English very well. So I often listen to Westen musics. There are many good musics and I like them. Then, I post blogs in English. I often look in my dictionary when I have trouble understanding the meaning of a word. Also, I sometimes study English grammar for my blog. It is difficult for me to understand English grammar, but I want to study it more and want to be useful for my blog. Then, I will take TOEIC test next time, so I will develop my vocabulary of English. I want to get a high score on the test. (109 words)
