I failed my graduating class and want to find a teacher.

Hello, teacher XXX, this is us. . . College students, just from. . . When I came out of the examination room, I felt very heavy and didn't hand in my ideal answer sheet. I remember when I first started this course this year, my tutor and seniors kindly told me that this course was too difficult to understand and digest. However, since I took your class from a teacher, I have been deeply attracted by this class. The teacher said humorously that he answered us one difficult question after another, which made me very moved and vowed to learn this course well. Unfortunately, something unexpected happened. Because I didn't work hard enough, I took part in many activities. Instead of catching up on my own road to knowledge, I was dragged further and further by others. I feel that I have failed such a good teacher arranged by the college. Later, when I woke up, the exam was coming. I had to seize every minute and make up my knowledge. Unfortunately, the last time was not enough. I didn't know until I got to the examination room that it was impossible to master knowledge without consolidating the topic. Teacher, I hope you can give me a chance to let go and pay more in the process of this paper. Thank you, teacher. I wish you all the best. . . My student number is. . . Name. . . Class. . . Thanks, teacher.
