Dear {Mr./Ms. Last Name}
I am sorry for my wrong behavior in your last class. . I had come to staff room to meet you after the lecture to apologies but you left for home. After that from last two days I am looking for you in the staff room to apologies but was not able to meet you. Therefore I am dropping you this apology letter.
I know I should have not back answer or raise my voice in the class. What I did was inexcusable, childish, distracting and disrespectful. I am more ashamed when you have not punished me for my wrong behavior, I am feeling very guilty about it. I am ready for any punishment that you give
You have always guided me, I see you as mentor and I always like your class. I promise to be a better student in the future.
Sincerely,
{Student}
