Dear Mr.Thompson,
I would like to apologize to you ______ in your class during the exam yesterday. I am so sorry that I looked in my textbook while I was talking the test. I feel terrible about _____ on the test. I know that this is not an acceptable excuse, but I did not have enough time to study for the test because I had a basketball game the night before it. I was so tired that, ____, I took a shower and went to bed ______. When I woke up, I remembered the test and tried to study. However, I managed to do that for only fifteen minutes.
Still, there is no justification for cheating, and I will accept _____ you give me without any complaint. I will also do my best to work hard in your class and to be as good a student as possible for the remainder of the semester.
Sincerely,
Peter Wilson
