Dear Sir/Madam,

I am writing to applying for a withdrawn from Course XXXX. I am so sorry that it is too difficulty for me to continue my study.

I have really tried hard on the course, and worked very hard on the study. However, after the second lessson, I still found that the course is not suitable for me. Therefore I apply for the withdrawn after the deadline of the application.

I hope that you can consider about my application carefully. I am looking forward to hearing from you.

Yours faithfully,

xxxx(Use faithfully,因為你不知對方姓什名誰)

Dear Sir/Madam,

I am writing to apply for my withdrawal from Course XXXX. I regret to inform you that I fail to catch up with the course.

I have worked hard and tried my best to accommodate the course, but after the second lesson, I still found myself fail to fit in the course. Therefore, I have to apply for the withdrawal even after the concerned deadline has expired.

I earnestly beg that you could kindly consider my withdrawal application. Thank you very much in advance for your kind assistance.

Yours faithfully,

xxxx
