My wife homeschooled our three kids all the way through K-12, our oldest enlisted in the Marines but the Navy wanted him bad for the nuke program. Being retired military and moving q3y, there are several "hoops" to jump through state wise but his saving grace is NC has (or had) a program that a student in HS can take classes for free (except books) at the college level, he had 24 CH completed, as far as a diploma goes, I made one up on the computer. That seemed to pacify the mil.
