Dear Prof. Richardson,

I am writing to inform you that I find the computer course too difficult for me. I want to know whether it's possible for me to choose a less challenging course.

Since students in the arts may not have much knowledge of math, finding it difficult to understand the numerous terms and figures in the computer course, let alone remember them. I acknowledge the importance of the course, but I simply cannot develop an interest in it. In fact, I find myself dozing off in class, no matter how hard I try to concentrate.

I feel miserable about this situation. To avoid further embarrassment, I request your guidance in choosing a less challenging course. I look forward to your decision.

Yours sincerely,

[Your Name]
