If you are eager to learn English, you must talk with your friends in English as much as you can and listen to English programs such as BBC news, etc at your leisure time.
I prepare my own lesson materials, in addition what you want to learn, that will be suitable to your level of English knowledge. It will help you to improve your English knowledge fast. I always prefer to give Japanese explanation too, and that will make a comfortable atmosphere for you to learn English.
Good Luck..!!
(Wakamatsu-ku, Yahatanishi-ku, Orio to Kokura, Orio to Nakama, Orio to Fukuma area will be better places to arrange the lessons)
