I got an offer of appointment to USMA and USNA. However, I received USNA first and was so overjoyed, I accepted it right on the spot. I didn't think that I would receive an offer from USMA but I got one 6 days after receiving USNA's. That's when I decided to really think about it and consider which academy fits my desires more for commissioning. I finally decided USMA so should I email USNA letting them know I have changed my mind? What is the proper way of informing the academies? My 7th semester is also a little weak compared to my other semesters, so is there a possibility that USMA might not want me anymore? I already sent in my 7th semester to USMA a couple weeks ago and nothing happened. I got all A's and two C's (in AP Physics 2 and AP Calc BC). Any advice would be appreciated?
