In cooperation with my advisor and classmates, I have completed a review of your offer for admission to graduate study at the
University of XXXX.
I have carefully considered all of your admission materials, and unfortunately your admission has not been accepted. Because the resources provided by your offer is not sufficient to accommodate the total demand for my graduate education, not all of those who give me an offer can be accepted. There are a great many excellent offers of admission & financial aids come to me, and therefore the final decision was very difficult.
I sincerely regret that I am unable to accept your admission, and hope that my decision will not dicourage you from offering further academic education or professional development to other students. Please accept my best wishes for success in your future endeavors.
Sincerely yours.
