Dear Mr./Ms. xx, Sorry for telling you that i want to resign to be the English Course Representative. I've learnt a lot as the Course Representative,but the main point is that i need to attend a lot of activities so that i don't have enough time to do the work well and study well. So far, i am not able to manage my time and do all the tings well. After careful consideration, I made up my mind to apply for the resignation.Please think about it. Thank you! Best Wishes, xx 日期 这是英文写作齐头式写法.
