I took a math exam last week, but I didn't expect that the question I thought was very simple was so difficult. I was dumbfounded when I got the test paper. I am sure to fail such a difficult topic. You have to be criticized by the teacher first, damn old man. Who told you to make such a difficult question? When I go home, I have to do both things by my parents. My ass may not sit on the bench for three or four days. Ah! Twenty minutes have passed, and I haven't even written my name. Forget it, just bite the bullet and write it down. No, I'll get a passing grade anyway. Ha ha, copy, copy, student coup! I wrote a little note first and threw it to my buddy. That boy is sure to pass. Later, my buddy will write a note. I picked up the note and was about to copy it when a cold light came and I couldn't help but make a tingle. Damn invigilator, I can't hide, because once I hide, he watches too much. I used my quick wits to pick up the paper, snorted, wiped my nose and threw it on the ground. The invigilator no longer has the courage to pick up that paper!
