一封询问信，请达人指教

卓芮UID: 2334757

Dear sir/madam,

I have received the conditional offer of master of conmerce(advanced) and there is one sentence that,quote, this offer is subject to the successful completion and maintain an overall average of 75% or better in your Bachelor degree studies at Xiamen University,unquote.
By now my average mark is less than 75%,which is about 70.68%(This score is the average mark of three years in my university).Because in the last year in my university I have only four subjects,it is impossible to get an overall average of 75% when I am graduated.And I want to ask whether I could be still accepted.




落款怎么写？自己英文水平不怎么好，这样写意思清楚了吧，老外能看懂吧？
