I am guessing u are academy cadet before? If so, this might help.
My wife and I were both USAF academy cadet and left voluntarily ( no academic, honor, misconduct etc)
She went to civilian school to complete her engineering degree and apply for direct commission, they ask her to write an essay to explain why she left at the first place and have to go to an extra interview.
Now is an officer and just got accepted for HPSP( the active duty one, separate from the the civilian one)
Hope this help, let me know if you have any other questions
