Why Am I Here?

There is a student who somehow went up Level 4 this semester.But he has speaking and listening problems as well as reading problems.
Sometime he can't understand what teachers and classmates say but he is acting as though he is the same Level as his classmates. So he has to study hard and trying it.
One day, he studied English until Late night. Afterword he went to bed . He was thinking about tomorrow's class and was falling into deep sleep. It happened that the next day, he actually woke up at 2:00pm. He forgot to set the alarm and he couldn't got up in time to go school. He got a shock! Although he did homework, he couldn't go to school. He made a mistake and a bad cycle was born.
However, he keep studying until late night so he always looks like sleepy and might not concentrate. But you don't care about him!
