While I was in junior middle school, I had great difficulties in learning maths. To change a situation, I made great efforts. Firstly, I bought some reference books and got prepared before class, make it easy for me to understand that the teacher would teach. Secondly, I listened attentive in class and took notes carefully, which help my accumulate basic knowledge. Thirdly I did my homework on time and turn to my teacher for help when I had problems. Finally I caught with others.

Nothing is impossible for a willing heart. Facing with challenges, I respond positively and overcome them.
