Work Hard!

I have been a college student for two months. And I'm still not used to studying in the university, sometime I didn't understand what are teacher talking, I can't get the point. Recently, I have getton the text in the class, then I got the bad score. I didn't know why, mybe I study in the wrong way or just didn't work hardly. I was little upset, why I so stupid, I can't study in good score. Then, I had a report about history, I also worked hardly, but the teacher still say my report was not good. God! Why I can't reach the teacher's standard! It's so setback. My pressure is much bigger, I can't breath. I wanted to do the best, but why I always loss. I really worked hard... ( >n<) Whatever, Just keep going!! I think keep working hard, I still have choice to sucee, if I won't do it, I still a losser.
