My determination

I want to come to be able to acquire English by this class. To achieve the target, I want to attend the class seriously. And, I want to come to be able to talk with a usual conversation with Mr.Wilson.The conversation of Mr.Wilson cannot be understood from my current English ability. I want to know what training to do to talk well with Mr.Wilson. If the training method exists, I think that I do hard. Please teach me the training method in which someone is effective.
