I (wake up) on the morning of the maths exam with a horrible feeling in my stomach. I knew that I (not study) enough the night before and that I was going to fail.
When I left home, it (rain) and there was a lot of traffic. I (arrive) five minutes late and the exam [?] (already / start). I sat down quickly and looked at the questions. I (not can) answer any of them! It was the most difficult exam the teacher (ever/ give) us.
I (sit) next to one of my friends called Sophie and I could see that she (write) very quickly. She was great at maths. Suddenly I had an idea. I (look) at the teacher, Mr Everitt. He (stand) by the window and he (not look) at us. I wrote a message on a piece of paper and (throw) it to Sophie. It said "I need help." Sophie (already/ finish) the exam. She copied the answers on a piece of paper and quickly passed it to me.
The following day Mr Everitt (call) us both to his room. We saw that he (hold) my exam paper, and Sophie's, too. He told us that we [?] (both/fail) the exam. We (write) exactly the same answers for every question, including several wrong answers.
