我想寫一封 formal的英文退修科目信，求指教

英文退修科目信
本人因工作繁忙關係，加上無法追上課程的進度，而感到很大的壓力，想暫時退修科目，望能保留學藉至下次重修。

Sample letter:

Administrative Secretary
Department of XXX
YYYY Institute

Dear Sir/Madam,

Withdrawal from ZZZ Course

This is to inform you that I wish to withdraw temporarily from the ZZZ Course in this academic year.

I am unable to pursue in studying any longer due the the pressure I am subject to as I have been unexpectedly busy in my day time job resulting in my lagging behind in the course work.

I request that my student registration with the Institute will stay so that I can return to do the course when my situation improves.

Thank you for your attention.

Yours faithfully,

__________
