Undergraduate / Grammar corrections on exchange student statements [4]

( If any grammer or word mistakes were found, please let me know! )

I am going to attend community college at Seattle from next April.
I have ever been other countries some times and I am used to go abroad, but it will be my first time to go by long term staying.

I am really nervous and afraid of attending classes.
But I am trying to improve skills while I stay in Japan.
I am writing essays, so I will post them lately :)

good night! - 23:55,Japan
