Dear Sir/Madam,

Sample Letter Of Request (Formal Letter)

Dear Sir,

I am writing this letter to inform you about my decision to stop taking the part-time evening course I enrolled for.

I currently work as an Assistant Editor for a publishing company and I recently enrolled in a part-time evening course In Creative Writing to help to build my skills. But lately, I have been held up at work and have not been able to attend the class frequently as I ought to.

This is due to the workload I have been assigned at work. There is a book publication going on at work and all editors are required to work overtime so we can meet up with the date set for the book launch. I have been assigned more tasks and it is very time consuming and requires all my attention. Hence why I need to stop the evening course for a while.

Therefore I humbly bid you permit me to attend the next available batch. This would be beneficial for me to regulate my office work and continue my course on the other hand.

Looking forward to hearing from you.

Yours Faithfully,
Bilton Mark
