Poor Exam

We had four subjects Calculus, Physics, physics experiment and military training had exam in this month, so I felt very busy and pressure. It was too suddently to prepare for all of the exam. However, what I do, it still could not read all of then. After the exam, I felt very depressed. I could not think what grade I got, because that most of the problems I could not do. I knew sad could not change anything, it was a big lesson. Fron now on, I decide to work hard in the class. When the next time, I will ready to the exam.
