First of all, I have to apologize for my short notice about windrow the course. I am writing this letter to explain the reason why I cannot continue the session.
Hope this letter finds you in radiant health and the best of spirits. This letter is being written to you to express my extreme gratitude for being a part of such an amazing short course.
I am one of your students who commenced my certification in graphic design. I am reaching out to inform you that I will be travelling back to my home, India and therefore, will not be able to continue the course.
