Study・・・

Good afernoon!!
I'm studying English and French. I had a lot of homework.
But I didn't do my homework. So I have to finish it immediately.
And there are English grammer and French test. If I don't
study, I will take bad mark. Therefore I must study.
But it is sleepy for me to study.
When I study, I always drink a coffee. I can concentrate on it.
I will do my best a little more.
