When I've been in primary school I was good student.
As soon as I've gone to the high school it has getting worse.
Before I've gone to the primary school, I had beed going to the kindergarten.
While I was cooking my dinner, my mother laught at me.
I've gone to my room after the dinner.
I'll be going to the high school until I'll be 19.
By the time, I'm going to the secondary school.
