too busy,so tired The end of this semester is coming. Every day is busy. And the next three weeks are exam weeks. I was quite busy in this semester. In the weekends, I did part time job and did lots of homework. So I seldom reviewed my lessons. Thus, as the exams coming, I have to review so many subjects these days. And there are so many contents in each book. It is challenging! The pressure makes me feel unhappy and tired.
