I'm currently at The Citadel and all I can say is that IF you do get accepted, take time out to see the institution and environment before making the decision to come. Make sure you are mentally and physically prepared. It's very tough here, I won't lie. Best of luck.
BTW, I was stuck on getting an AROTC scholarship as well, but once I arrived I changed my decision. Not saying that you will, but I can certainly tell you I am not the only person that has. I plan to go on to Law school. Then again, what really goes as planned anyway?
So can you further elaborate on like what to prepare for mentally or what to do physically? I have visited the campus twice and I really like it. I am also going for an AROTC and NROTC-Marine scholarship, why did you drop the scholarship and change your mind?
