There are a lot of storys about exams ,But I won’t forget that final exam , it is the most unforgetable. Before the exam ,I reviewed the lessons simply , although other classmates reviewed the lessons again and again .I thought that I remembered all the importances .I got too confident and relax myself .But I felt that I could give the best performance . When We began to examine ,I got really surprised .There were many questions that I could not answer . So I got a bad result . From then on ,I regard it as experience . It tells me that never be careless and too confident.
