Subject: Clarification on Physical Education Log
Dear Mrs. K,
I hope you are doing well. I noticed that I received a score of 45 out of 60 points for my Physical Education log, specifically regarding the question about whether I had completed any physical activities last week. I did engage in activities both last week and this week, and I submitted the PE log reflecting those activities. I apologize if there was any misunderstanding.
Thank you for your attention to this matter.
Best regards,
[Your Name]
