English study

I like to study English. So I want to study English more and more and take qualifications, TOEIC test and EIKEN. But I have no time to study enough.
I'm taking English lessons 4 times for a week now. I prepare for each English lessons at home. In fact, it isn't enough to study except for preparing for lessons. Because it is hard to go together study, part-time job and club activity. But I study hard to take TOEIC test in summer vacation. I want to learn English with enjoying and expand my knowledge about English.
