Dear Admissions Committee at XXX:
I am excited to inform you that I have just been notified of my grades for the Spring 2009 semester. I received a 4.0 GPA taking thirteen hours. My cumulative GPA will increase accordingly. I recently sent LSAC an updated transcript so you will be receiving it soon. I have checked your waitlist status online and am aware that you have received sufficient seat deposits at the beginning of May and that you will possibly review the waitlist come the middle of June. I would like you to know that XXX remains my number one choice and I will accept an offer immediately. My second seat deposit at my top choice that I have been accepted to thus far is soon approaching, so the sooner I can hear from you the better; but in the mean time I will continue to patiently wait. I wish you the best of luck in your decision making.
Sincerely,
Kels
How does this sound? I was thinking the third sentence may be unnecessary.
