Your post is kinda confusing. You said your security clearance was granted. (That is a conditional clearance) To attend the academy you need a conditional security clearance and a medical clearance. Full security clearances always take much longer but they will omit you from attending the academy only if a conditional was not granted. So if you have a conditional clearance then you should still only be waiting on medical. All of us are waiting on a full security clearance whether we have a FOL or attending the academy presently.
