Major In English

I have had never though I would major in English. I have had no idea why I did it. Since I had touched the subject of English, I always though it was hard for me to study it well. However, I wanted to study it well that could talk to others at least. By the way, the first thing to do is increasing my vocabulary. It's the basic thing to do to study English, right? Second is to know the rules about grammar. And the least thing is combining both of them, and using it correctly.
