I need vocabulary

I started study for EIKEN(English examination in Japan).

At first, I'm trying work book for vocabulary.
I tested English vocabulary at this site. And I found my vocabulary is about 4800 words. It's said that EIKEN Pre-1st Grade needs 7000 words. So I needs more vocabulary.

I don't know I can get more vocabulary till October's examination.
But I'll try it.

By the way, I have tried writing blog articles in English about for 1 month. I can write English articles without stress now.
I think improving English skill is continuing touch English.
We don't need it shame that we write and speak strange English especially Japanese.
