Summer vacation

I think I want to write about plan for my summer vacation.

I think I spend on extracurricular activities in this summer.
We are refraining from a big contest in this summer.
I am a member of the contest.
I was a member last year,too.

It has ended in a regrettable result last year.
I want to advance to the national athletic meeting only this year.

Summer vacation is practiced from 13 o'clock to 19:30 of every day.
There are no holiday extracurricular activities during summer vacation .

The practice is terribly tired.
However, I want to enjoy it.
