This is my 3rd time applying, and I have posted on SDN before that I have received over 100 allopathic rejections before receiving any acceptance (my first was an osteopathic acceptance in November). After making 4 waitlists, I sent in LOIs to all 4 schools and stated that if accepted I will 100% go there. Well yesterday, I called the admissions office at my second choice and found out I was accepted. When I got home, I had an acceptance at my first choice in the mailbox! I want to be an honest person but I can't fulfill my promise to each school. How should I tell my second choice no, and am I in any trouble here?
