Once in a math exam, the students were seriously answering questions, and there was a rustling sound of writing in the classroom. Soon, some students finished their answers and handed in their papers. Suddenly, a voice came from behind me. I clearly heard two students who handed in their papers discussing the answers. According to their answers, I checked my test paper carefully. Oh! One question is wrong. Change, I immediately flashed the idea in my mind. This problem is 8 points. It is a pity not to correct it. I just picked up the pen, but my hands were shaking. "Change or not", just as I hesitated, the bell rang. I put down my pen, stepped onto the platform and handed the test paper to the teacher.
Although I only got 92 points in this exam, I am very happy and have a clear conscience, because this is my real achievement. Through this exam, I learned a truth: be honest and trustworthy and don't cheat others.
