Today, I studied 3hours.
Recently, I have spent each day in study.
I try to get a qualification now.
The qualification that I try to get is very very very dificult.
So, I have to spend a lot of times for getting it.
But, I had ever spent 3 hours in study until yesterday.
Exactly, I spend 3 hours in study fou the first time in my life.
I have never studied earnestly.
I will have to spend a lot of time in study tomorrow too, if I want tu get qualification.
