Dear teacher:

Hello! I feel guilty because my exam results are not satisfactory. I failed to live up to your earnest teachings and ardent expectations, but I tried. This result is not what I want, because I also made careful review and preparation before the exam. Maybe if I really don't practice and don't work hard enough, I will work harder to make up for the shortcomings in the past. I know sometimes I don't take notes carefully in class. I didn't communicate with my classmates after class, but I will do all this well in the future, and I won't let you worry about such a result again. I know your concern and concern for me, so I won't let you worry and be disappointed in me again. Although I failed this exam, I won't give up the opportunity to wait for your praise in the future. I will continue to work hard because I want to see your admiring eyes. Teacher, I know it is useless to say sorry in this exam. I hope you can give me a chance to prove that I can do better in the exam. I know you will always support me. Thank you, teacher. Please forgive my mistake this time. I hope you will give me a comforting look when you see my test paper next time. Thank you.
