The exam was quite challenging. I had to think carefully about each question and make sure I was giving the best answer. I was quite nervous going into the exam, as I wanted to do well. Unfortunately, I only got 5 out of 25. I think the exam was difficult because the questions were quite complex and there were a lot of them. I think I could have done better if I had more time to think about the questions and if I had more knowledge of the subject. I'm disappointed with my result, but I'm determined to do better next time. What is the main idea of this paragraph?
