Wrong classroom

Jack was late. He was runnning up the steps when he triped. He dropped his book. The other students wachted him and laughed.
The bell rang and everybody started to go to the classrooms. Other students pushed Jack down the corridor and he couldnt in his classroom.
Jack found his classroom after a while, when he opened the door the teacher was sleeping and the students were doing an exam. Jack went to the desk sat down and started to read the paper, but he didnt understand anything, he didnt know what to do and he started to panic. The teacher woke up and he saw Jack, he was very surprised. He shouted- You're in the wrong classroom!!!!-.
