I bought the book of DUO.
But I still don't complete the book of Bayer.
I will listen the CD of Bayer every day.
And I will complete the bayer.
after,I think I will go next.
I talked study English with friend.
We got a good plan.
When we write diary, We watch a book of study English.
We will catch a word, and Synonym.
and We will get the use method.
