October 18, 2002 Dear Professor Smith, I am writing to discuss my homework assignment with you. I do not understand what I did wrong. On problem number five I only received partial credit. I felt that I deserved full credit for my work. I was wondering if you would please review my homework assignment. I hope you will see why I feel I deserve full credit. In conclusion, I really appreciate you taking your time to assist me with my concern. Sincerely, John
