Well, I don‘t wanna piss in anybody‘s cornflakes, but it is possible to join the RegF without a high school diploma and have an interesting career. 20 years ago, I left school with a partially completed grade 12 to join the Army. I could have chosen any trade I wanted according to the test results, but I went Infantry ‘cause that‘s what I wanted. Now I didn‘t miss any "employment opportunities" and was not bypassed by anyone... actually, I made WO in 16 years. Now last year, I decided to go back to school on weeknights to get my high school diploma. So I finally graduated 20 years later. And to top it all off, I was much more motivated and enjoyed it more. BUT... think about it... times have changed, so if it is possible for you to finish high school now, do it.
