the classroom. I was feeling nervously because I had not
prepared well for the exam. I went through the test several time,

exam, I put my book under the desk, opened it and started
looking for the answers. The teacher wasn’t looking at for me,

me for cheating. Instead, he gave me the second chance.walk→walked
