<p>In the past few years NAPS has only been the prep school for USNA and the CGA. The prep school for West point is MAPS. The Air Force Academy also has a prep school and so does USMMA-which is NMMI. I think, if you attend NAPS you owe an extra 3 months or so on top of your 5 years. If you drop out of NAPS or don’t go on to USNA nothing is owed.</p>
