An Sudden Attack

I have been worrying about my macroeconomics this whole week. On Monday we had the midterm unexpectedly. Before that, nobody told us that we will have macroeconomics midterm on the first day after spring break. After nine days playing with abandon, I almost had forgotten the name of the course, not to mention the details concerning the exam. Everybody have no idea that the professor will give us a sudden attack. It was funny that when the teacher handed out the papers, one of classmates stood out and said: “I am wondering if here anybody knows the answers of these questions? I never heard that before.” All classmates roared for his words, because maybe it was true that just few persons know how to answer the three questions. I glanced all the questions, and I toughly remember that the teacher did go over these questions, but I can’t memorize the answer at all. I searched my memories for all information about macroeconomics, but it did not work. Finally, I mostly handed in a blank paper that was just written several poor words. The results did come out by now. I was so worried that i am insomnia and lose appetite. I just hope the professor will not give me the lowest grades.
