Since you are in SoCal, a SAT has nothing to do with a J.C. I went to a J.C. (Citrus College; you know that school after all)transferred, then went to OCS and got my Commission. I never took the SAT or ACT. You have been on this site for awhile and I suggest that you finish college and get your degree. BTW I was commissioned at 28 so at 19 you have time. If you want to enlist, no harm no foul. Just know what you want and don't give up. There is a STG 3 on my ship now. Same age with a B.S. in computer science (or something to that effect) and worked for some major computer company. He enlisted because that is what he wanted to do and didn't want the chance to slip by.
