17 (born November 1999, graduated June 2017).

17-19. I was homeschooled, so I ended up "graduating" different subjects at different times. I then took a break of nearly 5 years and am now in the process of struggling through math and physics classes in college. It's freakin' great.

Graduated high school at 17. University at 21.

16

It's almost 8 years already damn

Would have been 17, but the school district I attended forced us to have a one required credit in each semester of our final year, and do a senior project.

So I ended up finally earning my release a few days after my 18th birthday, earning 6 unnecessary credits in my final year. The system was set up to rob motivated students from finishing school early and moving on to work or college.

As far as education went, I feel like I graduated from public school in 8th grade. Everything else I learned going forward came from other educational avenues, work, and real world experience.

I have always wished I had the opportunity to get out and get my career started earlier. If I could have got in the door at 14, I could have made another 500K in the 4 years that public school robbed from me, and be that much better set for retirement.

It is what it is though. I guess if I really had waned to, I could have dropped out, ran away from home, earned my GED, lied about my age and residents, and took the initiative, but I have never been brave enough to go that far out on limb.

16, skipped one year. (Born in March)

So graduating American High School is like finishing secondary in the UK and then finishing College after?
Yoo finish secondary school when you are 15/16. You leave to go onto college or sixth form and you leave that at 17/18. Depending on when your born. Academic years being in September and all that.
So for me it would be 17 because I finished all my work on time and passed each module/unit before the April which is when my birthday is.
