OK, I am currently enlisted in the Navy as an ET2. I have been in for 3 and a half years and am currently applying for OCS. I already have a degree in Secondary Education(got it before I joined, and don't ask). I am about to turn 33 and I know my options are really limited since I can only do certain programs, like supply, and still get a waiver for the age limit of 35. So what I am needing to know is what to study? If I am applying for supply, what test will I be taking, and what do I use to study with? My career counselor told me to get the Military Flight Aptitude book. Is this correct? Or is there something else? And are there any online resources to help study for this test?
