When I walked into the classroom, the teacher was handing in the tests. I was feeling very nervous. I had not studied at all the weekend as I had thought it would be easy test.
I went through the test for many times but I could only answer three out from the twenty questions. I did not want to fail the exam. Then , I put my book under my desk, opening it and started looking for the answer. The teacher wasn’t looking at me ,but I copied something. Suddenly, I felt a hand in my shoulder! The teacher caught me cheating. I don’t know what to say. Luckily, the teacher did not punish for cheating but instead gave me a second chance.
