I just received notice that my 3 year AD scholarship was upgraded to a 4 year one. It says that my 3 year scholarship to study physical therapy has been upgraded to a 4. The only problem is I no longer want to study physical therapy. I want to major in secondary education. Will I be allowed to do this? I really want to be an officer and serve, but I realize that PT is not for me. Any help would be greatly appreciated. Thanks in advance.
